Faulty phone

I upgraded my Vodacom contract on the 28/05/2015 at Craighall Vodashop. I selected a Samsung Galaxy S6 phone.<br> <br> The following week the phone started giving me problems. It did the following:<br> <br> o Dropped calls after no longer than 1 minute<br> o The sound went dead after speaking on the phone for no longer than 1 minute (I couldn't hear the person on the other end or the person couldn't hear me).<br> <br> I took the phone back to the store on 04/06/2015, after which I was informed the phone had to be sent away to be checked. I was informed yesterday that the phone was inspected and that nothing was wrong with the phone. I strongly dispute that for the following reasons:<br> <br> o A phone that drops calls 5 times per day is definitely not in a working order<br> o The phone was not checked in my everyday environment, so there is no way for any other person to say whether it is working or not<br> o I have been using my old phone (Samsung Galaxy S4) for the last week and it is working perfectly, so there must be an issue with the new phone.<br> <br> The shop requested that I email them with a complaint, which I did and have received no response.<br> <br> I think this is shocking service.
