Hisense Contact Centre is *******

Sent my phone in for a Warranty Repair on the 8th of January and received the device back on the 29th in a worse condition than i had sent it in. Device still did not want to charge and the rear cover was warped, and that's suppose to be a waterproof device, i could see into the back of the device, that's how badly warped the rear panel was, and imagine you cannot personally take out the battery as the rear panel cannot be opened by anyone besides the manufacturer. I tried calling their contact centre and was on hold for over an hour, i decided to drop the call whilst I was number 4, for over 30 minutes, I called back 10 minutes later to be number 21 in the que. Truly disappointing and unacceptable work ethics and service, no response to e-mails whatsoever.
