TELKOM IS A MESS AND ***********

I have a contract with Telkom to debit R135.00 p/m for mobile data on the 20th every month. On the 20/04/2022, Telkom failed to debit my savings account with R135 as per the contract and now they are charging me R335 for their own failure to debit my account. They debited my account on the 25/04/2022 and there were no funds in the account. The bank is charging me R90 for the unpaid debit on the 25/04/2022. I DO NOT HAVE A CLONTRACT WITH TELKOM TO DEBIT ON THE 25th. The call centre agents are just useless and they are very emotional, with poor listening skills
