Robbing customers

I purchased a Hisense 75inch smart 4k qled elite TV from makro Crown mines ok 25th November 2021 and it was delivered on the 26th of November 2021. It worked for two weeks, then I started experiencing sound issues and a lag on my tv. I called makro they told me to call hisense to fix the issue which was done. The hisense technician came through on 3 Jan 2022 he advised that he needs to order a new board for the tv and it will take two days. He arrived on the 6th and he was unable to open the tv. He took my tv to the hisense workshop the same and and since then I do not have a tv. We then where speaking back and forth and I was told by hisense to see the manager at makro Crown mines as My tv is unable to fix and they will replace with the exact same tv. My tv went to makro to and surprisingly I was told that I get a voucher and my tv is discounted. This is absolutely ridiculous I will not accept a voucher as I bought my tv on special and I will not be able to replace it for the voucher I receive. I paid alot of money and to be treated like this. Absolutely pathetic service both from hisense and makro. Robbing customers that spent alot of money on an item and it is a factory fault but I must suffer the consequences. Pathetic
