Vodacom keeps penalizing falsely.

Vodacom at it again. I complained about the same issue last month, but am i going to have to do this every month? I honestly cannot wait for my contract to come to an end. Vodacom keeps charging me pebaltu fees on pai account. Our agreement is for you to debit my account on the last day of the month but you keep debiting only after 10 days. I spoke to your consultant around the 7nt to ask when will my account be debited and she said only at the end of July but the following day an invoice that i owe vodacom was generated on my app. I had used some of the money because the consultant reassured me that i will be debited end of July. Vodacom tried to debit on the 8th returned unpaid, on the 10th i paid the account via the vodacom app as i was aware that vodacom tried to debit. Today i am suprised to find R100.88 penalties on an account that is R0.00. Vodacom consultants are feeding us lies.
