PEP CELLPHONE JABULANI MALL- ROBBING PEOPLE

I bought a phone from PEP on the 14th of March 2018 at the store and realized the simcard is not working then they advised to use my own simcard because their Rica system is offline, and she also told me that I have seven days to return the phone should I not be happy. I left the shop and when I got home to remove their simcard which was not ricard as explained by them then the phone refused to be on. On the 15th of March I went back to the shop to inform the cashier OMPHETSE MOSALA who then told me she has to take the phone in for repairs (the phone has been in my position in less than 24hours yet it needs to be repaired) she then took my ID and scanned it and took the phone and said I must come back in 3-6weeks. When I got home I informed my sisiter she was so shocked and told me what they said at the shop is not correct, how do they fix a phone that is one day old. I then went back to PEP @ 08h00 as they opened to tell them to give me my money, which they refused and I had to then take the phone back. ALL I WANT IS MY MONEY BACK ORR A NEW PHONE THAT WORKS PROPERLY. THIS IS ****************.
