Wrongly suspended account/

At the beginning of the month, my debit order bounced due to a shortfall of R10. I phoned Vodacom immediately and asked them to re-debit my account, they then agreed to debit on the 7th Aug '15, but they didn't debit, I then called Vodacom again and they still that they will debit my account on the 12th of Aug and even got a sms that they will debit on the 12th Aug but they did not debit again...so I gave it some time. then on the 19th of Aug Vodacom suspended my account due to non payment, I then called Vodacom and asked what was going on and they said they was a breach of contract but could not tell me why, I called again and requested that they un-suspend my line as there was no error on my side and that they re-submit my debit order, that was no success, so I then made an eft payment and called for them to open my line, in which I had to phone in more than 3 times for them to do so and then be placed on hold for long periods and then to be told that they are now going to charge me a fee for unlocking the line and furthermore this had affected my credit rating. Then after making the EFT payment, Vodacom then debits my account on the 24th of Aug after I had to make an EFT payment
