no customer care in port Elizabeth and bad service

I have three contracts with Vodacom.two of which is Lumia 520. I tried to take my phone in for technical advice but now I must pay R140 for their advice, people could not help me telephonically, basically I was told the Nokia Lumia gives problems, so why was I not told this before , I already had my phone repaired three times , my other Lumia screen broke, I won't bother to have it repaired, why must we pay now for a service which we got for free. I have over a yr to pay on my two phones I already cancelled my one contract
