Pathetic service

I had a very terrible experience with Telkom. I was contacted by the agent from Mondo on behalf of Telkom, offering me a contract phone. We agreed on the amount of R275 pm subscription, and an admin fee of R149, which was debited successfully from my account. I noticed that there was no debit for R275 on the last day of September 2021, as per our agreement. I called Mondo to find out about that, I was then reffered to Telkom. When I called Telkom, I was told that the debit order for R295 was cancelled from their side, and I'll be required to pay some penalties of R202, yet it's not my fault and also we never agreed on that amount of R295, yet R275. I was then advised to do manual payment of R295, of which I did. I then sent a statement so that when they charge me for those 'hidden fees' for their carelessness, I would be refunded. When I sent the statement I was told that the account number on my statement does not corespond with the one they have on their system. I called them, the consultant who assisted me updated them, however she said that i will still need to pay manually next month, as their system will still debit from the incorrect account, and I'll still need to pay penalties for that. Whenever I asked a question the consultant will keep me on hold for a long time. I never experienced such incompetence. I feel like Mondo and Telkom are just ******** me.
