thanx for breaking a working part

I previously complained a bout my phone not being fixed properly at the advance repair centre, well it came back for the second time and when I received my device i noticed that somehow it has passed vodacom's quality checks again with a new fault, my rear camera is not working. this is now the third time it has to go back to the advance repair centre who just can not manage to fix this phone. I do not want this phone anymore as every time it comes back with more problems and also If this is the level of customer care that Vodacom has I do not want this contract anymore as I'm paying for a service/item I do not have. new job no ***0. also your customer care does not work as no one can assist me in cancelling this contract as I cannot pay for a phone I do not have and is always broken and not due to me. if Vodacom wants the history they can look at my pervious complaint I lodged here where they promised it will come back properly fixed. I am now truly gatvol of this bad service. either replace this phone or terminate my contract. VODACOM STOP PASSING THE BUCK YOU SOLD ME THE DEVICE AND YOU HAVE NO PROBLEMS TAKING THE MONEY EVERY MONTH!!
