Hisense and Mikrolight bad customer service

Good day,

I would like to launch a formal complaint against Hisense's customer service.

i bought a hisense tv in 2018, October and within a week the TV wasnt turning on and a ticket was logged under this ********** 33 reference number. Microlight, the company that Hisense uses to for thier repairs gave me a as custome a very bad service. the main board was replaced and the tv worked but there was no sound, the engineer came after a few days to fix the sound issue. it took weeks of frustration as customer before the ticket was resolved.

i logged another ticket ( REF ********** 93 ) for the same tv with a broken USB over a week ago and an engineer from Microlight came to my house to have a look at the tv but unfortunmately we didnt get anywhere with him, he was so rude to my wife. The iisue remain pending.

Please investigate this matter
