Vodacom is draining my TymeBank account with failed debit order fees for a contract I don't have!

I am writing this in absolute distress. I app**** for a Vodacom contract that was NEVER successful. I have no phone, no SIM, and no Vodacom number. Yet, Vodacom keeps attempting to debit my TymeBank account. Because these debit orders are unauthorized, I do not keep money in that account for them. As a result, the debit orders are "unsuccessful," and TymeBank is charging me penalty fees every single time Vodacom tries their luck. My account is now sitting in a negative balance because of fees for a service I don't even have! I am trapped in a loop with the TOBi bot which is useless because it requires a Vodacom number—which I don't have! I demand: Vodacom must immediately stop attempting to debit my account. Vodacom must compensate me for the bank penalty fees incurred due to these failed unauthorized debits. A manager must contact me via email or my non-Vodacom number to confirm this is resolved.
