service, this does not excist at vodacom

I bought my Samsung 6 edge plus somewhere in September/ October. the phone did a factory reset or something and was blocked could not access it as it said I was not the main person. it was sent for repairs by mooirivier the 1st of November 2015 where they said it will take between 7 to 10 days to repair. 3 weeks later I received a sms stating that the phone was delivered to a branch in Brooklyn PTA, however I handed it in at mooirivier Potchefstroom, I phoned and went to vodashop mooiriver on the 24th where they saidthey will have it with them within the next 2 to 3 days. today the 2/12/2015 I went there they said that they are still waiting and that I must go to the potch service centre if I want to complain otherwise I will just have to wait. HOW MUST I JUST WAIT I am paying for the freaken phone that was mest up but they just don't give a rats ass. as they receive there money monthly so why does VODACOM have to care for you. I think I will take it up and find out how to cancel this contract as they simply don't care
