Ongoing struggle with Vodacom!!!

I took out a contract from Vodacom recently,and received a NEW phone.The phone gave me problems since the start.Vodacom said that they can't help me and they need to send the new phone to Johannesburg for repairs.I waited 6 weeks for my phone.After waiting patiently, I received my phone only to see that it still is doing EXACTLY the same and hasn't been touched.I phoned Vodacom and told them about the problem.I was told that they must send it away AGAIN and it can take ANOTHER 4-6 weeks.This is a BRAND NEW PHONE that was already sent to Johannesburg-according to them.Subsequently,I phoned the head office and the lady checked on the system.She said that the phone WAS NOT sent to Johannesburg and was lying at the Loch Logan branch THE ENTIRE TIME.All they did was swop the battery.Hence, I waited for 6 weeks and they told me that the phone was fixed in Johannesburg!So in essence, Vodacom **** to a paying customer. Vodacom should have given me a new phone when I took it in the first time,but instead, they **** to me
