The worst experience received from Pep ever!

My sister had the baddest experience buying a cell phone at pep within a week there was a problem with the charging block and she took it back to them as per their policy within 7 days to request a money back and the store did not want to refund or repair the phone all they had to say was that the phone is problematic alot of customers complaints about the phone in less than a month the phone started switching off never on a full day and she took it back and they send it in for repairs as they told her and when she went to follow up on the repairs of the phone found out that the phone was never send for repairs and they advised that the phone could not be repaired that is dugusting how you as a consumer can be treated by a respectable company like Pep where you paid for something and they blatantly refused to assist or abide by their policies. The attitude she received by the store assistant was disgusting they gave a email address of customer complaints and said she must send them a email how disgusting is that. I would not recommend anyone to buy a mobile device or any of their devices if this is how Pep treat its consumers. No reply from customer complaints nothing and the phone has been paid for but cannot be used its a Stylo Arctic phone. How disgusted can you be by this.
