Poor Service from Hisense and House and Home

I bought a Hisense 43" smart TV at house and home on 22 May 2022. On 1 Desember 2022 the TV can not turn and on the 2nd December I returned the TV back to house and home. After a week of waiting, the manager at House and Home claims that they are waiting for a technician. How long can it take for a technician to look at a TV and how long must I wait???? No body is answering my calls or enquiries and House and Home is saying it not the its Hisense. This TV is under warranty and its absolutely terrible that I must wait this long and have no TV
