PEP ULUNDI POOR CUSTOMER SERVICE

I bought a phone at PEP store Ulundi on the 6th April 2020. on the 28th May 2020 the screen went blank. I sent back to the store which they said they will send to the manufacture for repairs which was suppose to be 2 weeks. I have been trying to be in contact with the store and the Manager , but they keep sending me back and forth. this is now the third month waiting for the phone , and the Manager is now avoiding me. I am disgusted and angry with the way they are handling this matter and want nothing to do with their store. All I want is my phone back if they can't I want my money back.
