Appalling MTN Service

MTN's customer service is appalling. After upgrading my phone contract telephonically I 1. Received a revised contract which had a different colour phone to the one I ordered 2. After calling multiple times (and waiting 30 minutes+ on each occasion to simply be able to talk to a consultant in the Retentions department ), they confirmed that the colour I requested is the only one they have in stock, so the correct colour will arrive 3. The wrong colour phone arrived. I did not sign for it and rejected the delivery 4. Apparently the warehouse cannot find the phone I rejected, and therefore MTN cannot send me a new phone (how is this the customers problem?) 5. They don't reply to emails, they don't call back when they promise to. Each follow up takes hours and now I'm simply stuck without a new phone and within a contract I cannot cancel. Do not get a contract with MTN telephonically...Or perhaps with MTN at all.
