Shocking service - do not use this store!!!!

I upgraded my cell phone to a Samsung and after 5 days the phone stopped working (no one could hear me when I phoned them or they phoned me). According to the consultant if you have any issues with your phone within the first week you get a new phone. I took the phone in within the first week and then I was told that it needs to be booked in first 2 weeks thereafter and still no joy. I gave the phone in unlocked, I do not know how to put a lock on the phone. they are sending the phone back not assessed as someone put a lock on the phone and they will not replace or fix it. Do not use this Vodacom store their service is terrible and now I sit with an old Nokia and them claiming I put a lock on the phone when I did not or do not know how to<br> <br> Barret Edelstein
