MTN Breach of contract for 6 months now!!!

My husband got me a contract with MTN about 6 months ago. First of all the device that was delivered to my husband was not the device that was explained and sold to him in the call. The device sold to him was for a dual SIM device and he received a single SIM device. We complained about it and nothing was done. Since the first month on this contract we had major issues. The debt order goes off from my husbands account every month on the first. But the updating of the DATA, SMS's and airtime will only take affect on the 10th or the 15th of the month. He had fights with them about it and all that the call centre agents says is that it will update tonight. When you call tomorrow morning they will give you the same old story again. I have contacted my attorney and he informed me that this is a very good example of breach of contract. Well well MTN you will soon get a call from my attorney and I hope that you will have your ducks in a row as he will force you to mend all mistakes from the beginning or cancel the contract with immediate affect. MTN you can be sure that once that happens you can be sure that we will move our business to VodaCom.
