I bought a phone a pep cell south gate, phone is not charging and rude cashiers refuse to book it for repairs

Unhappy customer

I bought a cellc vogue cellphone IMEI: ********** ********** 0 at pep cell in South Gate mall on 09/03/2017. The phone was working ok but recently started giving me problems, the phone does not want to charge, I tryed using different chargers but it still does not charge. Today 12/10/2017 I visited Pep cell store in South Gate for a repair guarantee because accourding to my proof of purchase the phone has a 12 months repair guarantee. When I arrived at pep cell I explained to the cashier the problem i have with the phone, she tested the phone with her charger and still phone phone still didnt want to charge. She then said the problem is the chager not the phone but i tryed to explain that if its the charger why is the phone still charging with her charger that she used to test the phone. Another casher join the conversation and told me that i physically damaged the phone so there is nothing they can do to help me. I tryd to explain that this is not a physicall damage but the two cashiers verbally attacked me in front of other customers. I asked for a store manager but i was told that the manager is not around and will be back next week tuesday, so i should come back when the manager is back. Both cashiers had no name tags so i asked if they could give me their names so i can report this at pep head office, the ignored me and started serving other customers and after a short while, the only give me their names and refused to give me surnames. The name that i have been given is Siphokazi and Moipone, I am not sure if this is their real name or **** because the had no name tags. I am dissapointed because i am a regular pep store customer and I buy my phones at pep store but after todays encounter and rude behavoiur of the cashiers I dont think i will ever go to a pep store again.
