Poor Service

I upgraded my contract in October after a consultant called me. I recieved the phone on the 3rd November and on the 4th i realised that the speakers were not functioning. I took the phone to Istore and they confirmed that the speaker was non functional. I called Vodacom on *** where an agent said they will log a call to RAM to collect the gadget. This was supposed to happen within 14 days. I have been making follow up every week and to date that gadget has not been collected. Since the 4th the gadget is in its original packaging and not in use. On 1st December the upgrade package came into effect while there is still part of obligation by Vodacom that has not been met. This has been frustrating
