Poor/Bad Service from Vodacom

I tried on several to get assistance from Vodacom to address the issue of my account being on arrears. However, the response receive is completely unsatisfactory. I tried to get clarity of the response given but no clarity is given so far. The response given as follows:

Good Day

Kindly note that the credit have been processed to update the account. I have also notified our Subscriber Collections team to update your profile and account.

Regards Dominic

What I want to understand is the meaning of the account being credited. But when I check my online my account is still reflecting the arrears I am disputing. This really frustrating and also reflecting to me negatively as a bad payer and yet vodacom has my banking details at their disposal to debit the account on monthly basis. Can someone try to assist me on this. My worry is the next debit order date is soon approaching and I know Vodacom will debit the amount in question and yet is still under dispute. Hopefully somebody who is competent enough will be able to resolve this issue. I sent an email to Dominic trying to get clarity and so far no response.
