A Telstra customer has been trolling the company with photos of her cat for the last two weeks to highlight its poor service.

Sydney resident Laura Carrie bought a brand new 4K TV last month, and wanted fast, reliable cable internet so she could stream high-definition content on Netflix. So she switched over to Telstra.

The connection didn't work. After days of getting nowhere on the phone, she took to the company's Facebook page to try to get the connection issue sorted.

But instead of venting her anger at Telstra, Carrie, a social media manager and online business owner who needs the internet for work, began blogging her relationship with her cat, Kittie Smalls. It was a chance to renew their personal connection ... in the absence of an internet connection.
