Terrible service from MTN!!!

My colleague and I visited the store last week in order to take out a contract. We selected a wireless router for R169 pm (2 gigs) and were told that there wasn't stock at the moment, but that we would receive a call on Monday or Tuesday when the stock had arrived so that we could complete the rest of the paperwork. We submitted all of the supporting documents for the contract and signed a form. We received no call on Monday or Tuesday and when I called on Wednesday I was told that the man who had helped us was on leave and they had no idea what I was talking about. The lady hung up on us and when I called back, promised to call us back which she never did. I called again on Friday and spoke to a lady again who had no idea what I was talking about. I then asked to speak to a manager who was equally ***********. After being put on hold 4 times, I finally managed to speak to the man we originally dealt with who said that there was still no stock and he didn't know when they would have. He also said that he could not phone another store or the supplier. Vodacom has a more expensive product which I would now rather pay for, as MTN was completely *********** and impossible to deal with!
