******** treatment from Telkom

i took my phone for repairs at telkmo westgate mall on the 08.08.2015, and 3 weeks lateron the 01.09.2015 they called me to collect my phone . i take it home and still not working no report given why the phone wasnt fxed i took it back on the 02.09.2015 that was the second time it came back unfixed when refusing to take my phone without a proper explanaton on why my phone wsnt fixed thats when i was told that my I find was on , after switching it off on the 17.09.2015 which was now the third time it was taken back for repairs . now i get a sms saying that for my phone tobe repaired i need to pay as it is now out of warranty . I bught my phone on the 13.10.2014and my reciept says it has a 12 month warranty . question why must i pay if its still u nder warranty and was it pupposly delayed so that it can be over my warranty . there fact of the matter is i wont pay for it .
