Pathetic aftersales service

hi I logged a complaint on my Hisense TV on the 14-12-2021 And have been messed around from then . The unit was finally Collected 15-01-2022 a whole month later . The unit was sent back to my residence On the 20-01-2022 . On inspection found TV unit was still dusty and was not cleaned . As per receipt , Tcon Board was replaced . It’s very clear that the repair didn’t fix the TV .The screen looks worst now and the line at the bottom of the screen is still present . It’s very evident that this TV was not quality checked after the repair was complete . Furthermore , if the Tcon Board was really replaced on this TV unit , the back cover Should’ve been removed ,and cleaned . in my case this TV unit looks like it hasn’t been Open. I'm done mailing the customer care department , they are the most useless bunch of induvial I have ever come across. as for team management I left many messages but no one as gotten back to me .

please don't waste your time and money investing in these products , the aftersales service is pathetic !

I quote from the mail sent to Hisense on the 21-01-2022 "I will give Hisense by the end of this business day to get back to me on the way forward . From my side , I want this unit replaced , its clear that your repair center is useless ! and should Be closed DOWN ! . Hisense can also now compensate me for my down time without a TV unit , also for been messed around From December 2021 ."
