Bad service and lack of communication

I bought a cell phone hisense E50 at pep corkwood square in December. By the end of december the camera of the cell phone did not want to work. I reported to the store they said i must bring it in for repairs. I did which was the 6th of January 2022.i kept on going to the store to check the update of the phone because i did not have a cell phone. They said the cell phone is still in store The vodacom repairs in Greenacres P. E has not yet came to pick it up. I kept on going the to check. The repairs only went to go fetch it on the 9th of February 2022.I have been all this time with out a cell phone today the 26 of February 2022 i went to pep thy said thy call in on the 25 of February 2022 nd they said thy are waiting for parts. I did my own follow up same day i was told i should be refunded. The manager in the repairs when i called he refused saying the cell phone will to ready on the 28 of February. I asked what about the parts you were waiting for. He refused now they want to give me a phone that is done in a rush because they dont want to credit me. The phone has been long time away from me.,i dnt understand why i must suffer for their bad customer service. I want my refund back
