To whom it may concern

My name is Griffin May and I have a serious issue with your terrible service. I lodged my repair request on 08/10/2020 the number is *** and after alot of back and forth and heavy struggles and complications as well as several different repair requests my TV was finally collected over a month later on 16/11/2020. After alot of requests and haggling it was finally returned to me on 10/12/2020 with repair number *** but to my surprise nothing has been done to my TV. It came back dusty and with the same issue if not worse. Is this the kind of service that you render to your customers? After two long months and one month without a TV I am no better off than I was when I started this process. It is really disconcerting to me because I have 5 Hisense products and if this is the standard of service that you provide I am really dissapointed and I will not be purchasing another Hisense product and I will spread the word as well on all social media platforms and complaints and apps. This can also not solely be blamed on the COVID-19 pandemic because my TV has not been fixed which means its a complete disregard to me as a customer and I am really disguted! I expect that my issue will be resolved swiftly and with haste.

My contact details are ***
