Poor Customer Services

I always hear people complaining of poor customer service from MTN & I have finally experienced it myself. I took my phone in for repairs/evaluation on 6 April 2015 and was told I would have it back in 3 weeks. This has not happenned. I phoned *** on 28/04/2015 and spoke with Phillip. He told me they were expecting stock within the week & they would call me. This never hapenned. I have called the same number several times today and the phone just rings with no answer. It's been almost a month without my phone - and yet you still collect your full debit order from my account - yet techically I only have half the package! This is ****************!!! No one has even bothered to phone me to inform me if stock is delayed or there is no stock, just nothing but silence! This is disappointing from such a big company who should know better especially when it comes to Customer Care! I want my phone!!!!!
