Telkom suspended my account even though I should be having a credit on my account due to double deductions for two months in succession

My Telkom business mobile was suspended even though Telkom deduct my debit order every month. I missed my payment in December for one reason or another. Telkom recovered that by double debiting me in January 2022. They double debited me again in February but suspended my service on the 7th March 2022, claiming that I owe them money on my account. When I called them to enquire, they claim that my account was handed over to their collections department, and it is the collections department that deducted from my bank account but were not crediting my Telkom mobile account. I was then told that the issue would be escalated to their collections department and my account would be restored. Since then, I have been calling them each day to find out why my account is still suspended, and I still cannot get a satisfactory answer, and my account has not been restored today, which is bad for my business. FYI my account number with Telkom is ***
