Pathetic service from store manager Jali

I logged a complaint regarding the cellphone I purchased at Vodacom 4 u Southgate. Huawei y5lite 2019 purchased last Thursday. The phone gave me a problem same day not reading my memory card. I went back to the store after contacting manager Jali. Day 3 I went to store of which Kallie fixed the phone, I came back home then following day I encountered same problem. My daughter went back to the store after I contacted Jali again and phone was taken to vodacom shop where my daughter said another guy fixed it but when she got home the phone had the same memory card error. Yesterday the error message changed to memory card unexpectedly removed but memory card is still on the phone.

I called customer care and spoke to Kamogelo I told her that I want someone who is a mediator between the store and customer because I'm now tired of this phone. Memory card works on all phones in my house except this phone. She called the store and the nerve of the branch manager, he told Kamogelo that when I left with the phone I was happy, how was I gonna know when I get home and put my memory card it will not work. He said that I will be charged 250 for courrier and the phone Wil be taken for repairs. A phone that was returned within the 7 day period twice? Does he think I'm stupid and I don't know my rights as a consumer? I Wil never buy a phone that will be fixed or repaired with 10 days. If it gave me problems within a day what is going to happen in the future?

He doesn't even consider the phone came back twice in the store at my cost? Manager Jali thinks I'm stupid, I want a new phone or my money back. I want this matter to be escalated to the Regional manager. I only want to be contacted and told that I'm going to get a new phone or my money back.
