Hi-Fi Corp Mall of Africa iPhone ****!!!!

I bought an iPhone for 3k on Black Friday, it had a battery and rebooting problem after 4 months of buying it. I took it back for repairs as I was told it had a year warranty..The phone came back from repairs and it was still not charging/rebooting, I was forced to sign that I collected it and to buy a new charger for it... After laying a complaint with the manager,the phone was booked for repairs again and I was shortly informed that I had to pay R3500 for the phone to be repaired by their supplier Vodacom!!!
