PEP store white river crossing and Sumsung

I bought a Samsung AO2 at PEP store white river crossing for my daughter as a Christmas gift mid November 2021, she only used the phone for two weeks and it started giving her an error, I took the phone back to PEP store and the Manager said its not reading the SIM card they need to send it back so they can check what is the problem and they will give me a call in 4-5 business days, no one called me for any update, after i went to the store i received an SMS on the 11 January 2022 which i did not understand again drive back to PEP store and one of the sales consultant phone the number on the SMS to finf out and they told her that the phone has a software problem and I have to pay for it to be fixed. I asked to talk to the Manager because Im not willing to pay for a software of a phone tgat was used for only 2 weeks and I was told the Manager is not there I must come back again on Friday. I went back again on Friday and the Manager phone the same number where I hold for more than 45 minutes with a consultant Named Thulani Mathibela from Samsung and he promised that someone will call me in 2 working days now has 4 working days and no one has come back to me. I'm so angry and fed up with their service and all I want now is my money back. Because seriously I paid for something which not even using for a month now. Poor and disgusting service on both PEP STORE AND SUMSUNG.
