Vodacom is *****ing my money No way to speak to Accounts department

I cancelled all my Vodacom contracts by getting premature cancellation requests from Vodacom. I paid the amounts and sent the proof of purchase to *** in October. I received reference numbers that all my accounts were closed with Vodacom. They still did not cancel my debit order and deducted money from my account on 2020-10-30 R325.37 and again on 2020-11-30 R671.57. I called numerous times about this issue with NO clear answer. Client service just rec=vert my query to back office. I am a prepaid customer so I can't phone cancellations and I can't speak to somebody in accounts. This is ***** and I will take all my evidence to the ombudsman. The money above must be credited back into my account as soon as possible
