THERE are overdraws from your bank account and then there is what happened to one Sydney man.

Calum Mawson was victim to what he calls “a classic stitch up” after noticing his Commonwealth Bank account had been overdrawn by an amount of $2,250,623.00.

Yes, you read that correctly — his account had been overdrawn by more than $2 million dollars.

The mishap stemmed from a Telstra bill the club promoter had received for $225.

After paying the bill online last Friday, he received a confirmation email from the Aussie telco.

However, instead of confirming the amount of $225, he was advised of the rather large payment.

“Thank you for paying $2250623.00 on your account *********** which we received on 20/05/2016,” the email read.

Mr Mawson immediately called Telstra to advise the company of the glitch.

“When I got the email I called customer service and I was told not to worry as the payment would not go through,” he told news.com.au.

Believing he would only be charged the $225 he initially went to pay, Mr Mawson went about his weekend as normal, until the worst case scenario occurred the following morning.

“I woke up at my friend’s house and went to order an Uber, but was advised I had insufficient funds to order the service. I knew I had the money, so thought this was a little strange,” he said.

“I then checked my Commbank account and saw that I had been overcharged by the millions.

“I was completely gobsmacked at the amount, I have never seen so much money in my life.”

The 22-year-old said he was quickly on the phone to both Commonwealth Bank and Telstra, but was finding it hard to get answers.

“For its part, Commonwealth was very helpful and told me it would be sorted as quickly as possible and a customer relations officer kept me in the loop.”

Mr Mawson said although the money was returned to his account, he had a very stressful three-day wait.

“Commonwealth reversed all the fees and said it wouldn’t affect my credit rating, but I was still without money for a number of days,” he said.

“It was a huge burden and I wasn’t able to do anything at all.”

While Telstra is apologetic for the inconvenience, it claims the issue was from user error and nothing to do with the payment portal.

The telco claimed the payment was only pending and not processed, only occurring because he entered the wrong amount in the payment line.

“We are sorry the customer has experienced this but this is the result of accidental user error,” a spokesman told news.com.au

“We have worked with him and his financial institution to resolve the issue.”

These are claims that Mr Mawson refutes, saying he is confident he only entered in three digits.

“Telstra has been so unhelpful throughout the whole experience and customer service just kept trying to push the blame,” he said.

“I think Telstra are the ones to blame in this scenario and what makes things worse is the fact they haven’t even reached out to offer any sort of compensation.”

When asked what he would like to see done, Mr Mawson said he doesn’t have the answers because he finds it so hard to believe it happened in the first place.

“I don’t think I will ever feel comfortable paying an online bill with Telstra ever again,” he said.

While currently on a contract with the telco, Mr Mawson said he would be swapping providers as soon as possible.

“They have just left me hanging and I feel like they don’t even care,” he said. “It’s just the latest in all of its sh**ty service.”

To add further insult to injury, just hours before the publishing this news.com.au article Mr Mawson received an email from Telstra advising him that his bill was yet to be paid and he was required to do so.

Something he describes as a “right f***ing stitch”.

Commonwealth Bank said it was upset the incident occurred, but happy it could help fix the issue.

“This scenario can be an upsetting time for anyone and Commonwealth Bank worked with our customer to fix this for him. We understand errors such as this can be distressing for anyone and we always want to ensure we can assist as soon as we can,” a spokesman told news.com.au.

“When making bill payments or account transfers it is important to double check all amounts and details you enter. Customers can always contact Commonwealth Bank any time of the day or night on 13 2221 if they require any assistance or to report any mistakes or unusual activity on their accounts.”

The news adds to what has been a horror 2016 for Telstra, after suffering four major network outages that have left customers seething.

The fourth major outage took place over the weekend and left 375,000 phone and internet customers across the country unable to get online.

Despite claiming the problem has been fixed, social media is still privy with angry customers claiming to be without internet for a fifth day straight.

Stupid @Telstra 5 days without internet. Cant do any work done. When is it gonna be fixed. 6280. — Janine (@JanineMuir1987) May 24, 2016

This came two weeks after Telstra’s chief operations officer Kate McKenzie announced a $50 million solution to fix the troubled network, which would include new equipment and new procedures.

The telco also had two network outages in March, forcing chief executive Andrew Penn to issue a grovelling apology, in which he accepted full responsibility for the problem and offered customers a “free” data day.

Additionally, millions of customers were left without mobile phone voice and data services in February as the result of what Telstra described as “human error”.
