Substandard Hisense Product & Poor Service

I purchased a Hisenseinfo 65” smart Tv In November 2019. TV did not connect to internet, would freeze & fade & go bright. Took almost 3-months for them to replace. New TV same issue. Understandable we are in lockdown but I received a call for them to replace AGAIN. Despite my mails Hisense have not reverted. & I have to use my laptop to connect to Netflix. Really shocking service & substandard product.
