Unhappy Customer

Ive been a generally happy customer over the last 10 years, until now. i upgraded my contract in Sept 2015 (which by the way I didnt get a copy of the new contract, but that's not my problem) <br> <br> My problem is the sales person pitched the Samsung Galaxy J1 phone to me as this really great, affordable phone. So i took it, to my dismay the phone is extremely slow, it doesnt open up my apps like facebook, messanger, instagram and BBM. But that i could still live with, as frustrating as it is. My biggest gripe came when my phone's volume suddenly dropped, even though it was on the loudest setting which meant that I now cant hear my phone ring and now the ringer sounds like a hollow tin so listening to music on my phone is not a pleasure.<br> <br> I sent it in to the vodacom repair centre in Westgate Mall, from there it went to Cresta and from there it went to an \advanced repair centre"according to my sms updates. 3 weeks later I get a message my phone is ready for collection. i happily go pick it up"
