PEP Cell - No go

On the 17/04/2023 i went to PEP at overport city and purchased a cell phone. before we could purchase the phone only the warranty was explained to my husband and myself, when the receipt was given to us to sign the terms on it was not indicated or expalined by the sales person Luanne. The phone started to give us issues( freezing, going blank, extremely slow.) On the 08/05/2023 we had taken the phone back and wanted a refund cos we were really angry about buying a new phone and having so many issues. We are told that we cannot get a refund as we signed the receipt which indicates that the phone can only be returned within the first 7 days of purchase, when will anything give you a problem in the first 7 days. Luanne first approached us so we explained the problem, she advised that we cannot get a refund, she then called Nqobile and Luanne despaired into the store, nqobile explained the same thing without even trying to check the phone to see the problem. She then told me to call customer care and went into another room. I called customer care only to be told that the store was to call PEP cell customer care, which Nqobile had no clue about, we asked to speak to a manager, we were advised that the manager is on leave, and they do not have the bosses number. Nqobile called PEP cell customer care and called me to me speak to an agent after waiting for 5-7 minutes at the counter. The agent said they can take the phone and send it for repairs which may take up to 30days to fix. they were not even willing to give us a replacement phone. We were more than angry now, The number is our business number. how do we operate without a phone. Nqobile apparently call the regional manager who was giving us the same answers. This was worst experience that we ever had. Please if i could put a sign outside PEP and advise people not to buy phones from them. They did not even a technician at the store. the staff are even clueless about phones. how are they selling phones. Luanne and Nqobile should have more customer service training.
