******** debit orders

After getting retrenched in 2019, I called telkom to ask for removal of debit order, they said it's not possible to do that and provided me with the Easy pay number at retail stores. Since then I've been paying without fail yet they still debited me. On 10 November I called and my query was escalated to a manager called Ntuthuko who still maintained that I must deposit R49 into my bank account for debit order on top of manual payments received on their side every month. Please help me.
