Vodacom billing different people for same account

We have been trying for more than a year to get a transfer of ownership done (from me to my daughter). Every time Vodacom tells us the papers got lots or they just have no answers. About 5 months ago we finally managed to get Vodacom to transfer the account over to my daughter. She was told that there was an outstanding amount on the account, and that she cannot take ownership before the amount was settled. She paid the amount and then they completed the transfer. Problem is that they deducted the monthly premium from the wrong account. For WEEKS we tried to sort this out, but all we ever hear from Vodacom is “the system is offline”. So instead of paying per debit order, she has been using the Vodacom app to do monthly payments and make sure everything is up to date. Vodacom is getting payment from the new owner, but still trying to get monthly premiums from me as well. So not only are they trying to get double payment, they also add interest to an account that IS NOT BEHIND on payments. According to one of the customer service agents, the account is actually paid up months in advance. To top it all, they handed my account over for debt collection, effectively destroying a perfect credit record.
