Upgrades and Strikes/Misleading customers

We went to upgrade on the 10th of May at our nearest MTN shop.We chose our handsets and then they told us they have no stock,we must wait about a week or so.After a week I phoned just to hear that no handsets will be delivered due to a strike.Fine,I understand.But then about two weeks after we went to upgrade we got a call from MTN saying that since we have been loyal customers for such a long time we will get a monthly discount on our contracts and that new simcards and our handsets will be delivered to our door because of the strike.ALL that was delivered was new simcards - NO HANDSETS.I have been trying to sort this out,phoning different numbers and NOBODY can seem to help me.If I DO NOT get a responce on my complaint and this matter is not resolved by the end of August I will cancel my debit order at the bank.Its just rediculous.MTN USED to be THE BEST but not anymore.I am sure I am not the only unhappy customer.
