Bad service

Good day

My name is Tshameleni on the 13/02/2021 I purchased an phone (samsug A11) on my truworths account. I asked the sales consultant that since the phone is a different network provider as the one that I'm using won't it be a problem and she said no it won't be.the phone I purchased at one of your shops at Giyani Masingata mall.I returned it as the phone I could not receive any calls from it I was told to do an swim swap of which I did but still the phone didn't work.i returned it and it was taken to repairs.i paid my monthly installment for a phone that I don't have (which I didn't mind because I had hope that my phone was going to come back).it finally came back and the same problem it was still there/giving me.The problem is that when I'm at home I can't receive any calls but when I'm not at home I can. during the time when my phone was at repairs I bought another phone and its working perfectly at home and every else.on the 12th of March I went back to the store to report the very same problem I even asked them to accompany me home so that they can see what I'm complaining about they didn't agree with me but was told to come back on Monday 15/03/2021 or change my number.I left the phone at the shop.My bought another phone from a different shop the same phone that I asked to be changed to and truworths sales consultant refused.i no longer need the phone from truworThs I need the amount to be reversed from my account as the phone is no longer in my position it's with truworths Giyani and I already bought a new gone. Kind regards Tshameleni
