Homechoice repairs

It's Glodia I'm not happy with home choice I returned a speaker on the 3rd of Feb 2025 because it was giving me problems..i did follow up after the whole month since there was no communication on their side. I was told the speaker could not be fixed so repairs was waiting for hisense to give authorization for new speaker, a month later I was told they couldn't find the speakers serial number.. On the 28 March curior guy called me with my parcel I was happy thinking the matter has been resolved to my surprise they brought back the same old speaker with the same problems. I went to the store ask them they told me to call head office I did and the lady said I should return the speaker to the store, I don't understand why they give me back the speaker if it's not fixed and there is R534. 81 that I have to pay I don't know for what when Im the one doing up and downs im really hurt Yoh homechoice.
