Disgusting service

I purchased a new contract with Vodacom (Huawei G6) a few months ago. Unfortunately the phone stopped working for no reason and we took it in for repairs at the Cresta Vodacom branch. For 3 weeks we had to chase up in regards to this and then were told that this model is no longer in production and that we had to get a different phone in its place. I came into the branch last weekend and the consultant (who was so arrogant that he even refused to give me his name) said our only option was to pay in almost R 1 000 to get another phone at the same monthly contract rate. I asked to speak to the manager Nathi Nsukwini who promised to come back to me on the 7th of April. After calling numerous times over the last 3 days I am left with no choice but to complain about the disgusting service. Every time we called Nathi was busy with other clients and promised to call back but never did. For almost a month now we do not have a phone for which we are paying, is this how you treat your customers?
