sim swab nightmares

I had a contract with Telkom which ended two years ago, they were debiting from my bank account. Then I wanted a new contract with them this year again, all went well I got my new phone Samsung s22+ with a new sim card. Now I need to do sim swab, for the services to be loaded on the old sim card. They say I owe them R1.95 from the previous contract that ended two years ago. When I ask why they say financial advisor was supposed to call and ask me to pay that money since is so little that they cannot invoice and debit it, so now my account is blocked for that reason. In-store, they cannot help since this account is handled by the online people who works Monday to Friday and they cannot even log a call for me to get assisted. I called online which I got different stories, I asked an account to pay that R1.95 since they cannot debit that money with the new debit account. The lady who assisted me on the phone sent banking details which was only bank account and branch code. I did payment on the 6 July 2022 and they said I must wait for 24-48 hours for the money to reflect. On the 10th I called again, the money was not cleared, I did send them proof of payment. Even today the money has not been reflected on their account when I call they said I choose the wrong option I must select accounts department from the option services. When I select that option, they read my balance airtime and data from the phone, I cannot go through to consultant. I am stuck with two sim card and payment that is running on the air.
