Hired an Electrical Engineer that has not delivered files as promised, overcharged, and went AWOL. Upwork has been AWOL as well. I hired ****** ****** an electrical engineer, via Upwork on July 10th, 2020 to create a Printed Circuit Board design. We agreed to 100 hours of work to complete. When the 100 hours had transpired, ****** contacted me the last day he was able to bill me and told me that the design would be an extra 40 hours of work (an additional ******** I was upset and surprised at this but weighed out the cost of starting from scratch with a new electrical engineer and opted to let Mr. ***** finish the job. At the end of this additional 40 hours, Mr. ***** proceeded to make excuses as to why he was not finishing up the job and delivering the schematic and bom files as promised, even citing "girl trouble". I tried to keep things professional and sincere by telling him that I hope things work out with him and his lady, and waited. At this time, Friday, August 7th, 2020 at 11:12am Mr. Burns messaged me that he had "completed the design and I'll deliver the results when I get home back immediately." That never happened. I have since then requested the finished files from Mr. ***** to no avail. During this entire time, I have been attempting to contact anyone at Upwork, also to no avail. In the past 2 weeks, I have left 6 messages with Upwork with zero response. Today I spoke with a new electrical engineer about doing this job for me and will be hiring and working with them moving forward. I also filed disputes with American Express for all charges relating to this incident totaling ********** At this point, I have lost valuable time, and as of right now until these charges are put back onto my American Express card, ********** I cannot, in good conscience, continue a working relationship with Mr. Burns or seek the services of Upwork due to breach of contract on Mr Burns part, and the non-responsiveness of Upwork. It's simply unprofessional on both parts. I paid in good faith, and waited. ***note: the attached file titled "PCB Design updated agreement XXXXXX_signed.pdf" is an additional agreement past the NDA that was signed on July 10th outlining my expectations for Mr. Burns which he signed and returned.
