Hisense is dissapointing

I have never experienced such bad service, my tv is not working and my warranty is still valid.i took it to game store alberton where i bought it, this was on the 22 may 2019. They checked it and told me to go back home with the tv and a hisense technician will be sent to my address and fix it there. On friday the 24th i called Game store since no one contacted me and i was told my documents were submitted in the morning to Hisense. I recieved a call on the 28th from hisense and they confirmed that they will come for repair, they arrived after around 2pm and could not fix the problem and they said there is a part needed and they will come back by thursday to fix should they get the part. To my surprise an sms with reference saying the tv was repaird came through. i immidietly called help desk and questioned the sms, the lady told me the part is not available on stock therefore i will be given a new unit. i was told to call friday the 31st if i dont recieve their call. on friday around 10am when i called hisense i was told there is no such thing as getting another unit instead they will send people to fetch the tv for repair, I asked if it was to be repaired why didnt the technicians take it. This is waste of time and my airtime. The guy had no respond as to weather it will be repaired or replaced. I asked for a senior person to contact me urgently and the guy said he will make sure they call me. I kept calling every 2 hrs and no senior person contacted me. I called 5 times till 16h30 whwn they were cutting off my call. I also sent an email same friday during the day asking for a senior person to call and I recieved a response on saturday saying the tv will be collected for repairs, no apology or confirmation of when it will be collected. Today its tuesday abd no one has contacted me to tell me when the tv will be collected, i paid my monthly dstv subscription but cant even watch the tv. I dont owe hisense a cent and their service is disgusting. Someone should come collect the unit, next time i will think twice when i see hisense. reference number is ********** 42
