Network with *********** accounts department

We have 4 contracts with Vodacom. Due to this lockdown one month's instalment was not paid. We spoke to numerous consultants after spending a lot of time waiting on the phone and were told that the full balance o the account would be debited . At the end of May 2020 Vodacom debited the account but only for 1 months charges leaving the 1 month plus interest on that as unpaid. We again made numerous calls to them and then even went into the branch at the Pavilion and spoke via the branch consultant to another consultant named Ismail who assured us that they would debit the account within 24 hours for the balance. It's now gone 2 days and still the account has not been debited. Also there is an added bundle on the account which vodacom continues to add every month and add charges for it to the account. This they refuse to cancel until the account is " paid up to date". I have to wonder if this is not deliberately being done. I'm practically begging them to take the money I owe them and they refuse. But continue to add interest to it and refuse to cancel any additions until up to date. I have to wonder if this is not so they can make more money off their customers. The added bundle was accidentally done via the Red hot offers for 1 month only. We thought it would come off the airtime but o calling the call centre they said it does not come off airtime but rather is charged seperately. We are now stuck with this situation and considering taking it further if it is not sorted out asap. They also block one of the cell phones randomly On the basis of the balance and don't send banking details either.
