Telkom strikes again!

I have been TRYING to get in touch with Telkom since March 2021. My account was supposedly handed over to Nu Debt. I set up a payment plan with them. Since then, Nu Debt claim to have passed my account back to Telkom, I have tried to then contact Telkom to sort out the payment plan as Telkom CONSTANTLY debited the full amount from my account. THSI IS LUDICROUS! I am so angry with Telkom and their poor customer service. I would like someone to contact me immediately. Otherwise I will have to make an attempt to escalate this from my side.
