Telkom suspended account due to rejection fee

Telkom have suspended my account, saying I owe R621 for rejection fee which I find it unfair as I always pay my account via eft. I had sent numerous emails, even made a call. I was told that there was a request for the debit order, I then asked for the proof, until this day I did not get any proof yet my account is suspended saying I owe the amount for the rejection fee on my bank account. What surprises me is that I have been paying via eft for the past 3 years and I never had such fee ,why now. I missed my class as I had no wifi. My April statement had all those rejection fee, which I queries. Then my may statement it was removed, thereafer I paid as normal the agreed amount as per contract. Now they tell me my account has been suspended.

I want them to proof that I made the changes until today no answer on this. I need my account amended immediately as I use it for school classes, I cannot afford to miss class. I have paid for the June period yet they suspended it.

Please I urgently need help on this matter. I tried to communicate with Telkom but they hear me not.

Thank you
