Faulty device

I have experienced shocking service from Vodacom. After numerous queries regarding my faulty device, I have sent follow up e-mails but until today I have not had any response whatsoever. <br> <br> At the moment I am sitting with a faulty device that could not be repaired within the warranty period and now that this period has expired, Vodacom says they cannot repair the device as this is now deemed beyond economical repair. They only found this out after the phone has been sent in 4 times already, this being the 5th.<br> <br> Your internal complaint system does not work, I have sent an email on 08 October, and again a follow up on the 22th, but nothing yet, extremely bad service from such a big company.
