*********** and *****ing your money

Had a 2 year contract with Vodacom, we cancelled the contract and they gave us a statement of what we still have to pay. We paid that exact amount within 6 days and they said the contract was cancelled. But still they debited the money each month after it was cancelled. We stopped the debit order after the 2nd month that they debited it. We spoke to Vodacom numerous times to correct the mistake but nothing was done. About a month ago we got an email saying that the account is handed over to their lawyers. We spoke to Vodacoms lawyer, sent them all the proof that the account was payed and that Vodacom actually owes us money. They said that it will be sorted and they can see that the problem is on Vodacoms side. Only to find out yesterday that it is STILL NOT sorted. They've put us on ITC because we are "slow payers". We were in the process of getting a new car but can't because of Vodacoms incompetence.
