Telkom billing dispute

Hi i cancelled my contract with telkom in jan 2021 because i spoke too a consultant and they told me i should make an immediate cancellation in January. After doing that they still debiting my account up until now. Ive spoken too a consultant an she told me because i reversed the debit order at 1 time im gona have too pay a fee of R202 which i did an the R169 that they say i owed them that was in Feb. The 15th of march they debit again anni left it i phoned in again an they tell me its the last debit order that goin off. I check my bank account i c they tried too debit again because i moved my funds too another account of mine before the 15th. I need help plz how can i get these ppl too stop because calling them an speaking too a consultant doesnt help should i go too the store itself?
