Cancelled contract but debit order still being taking

I cancelled my vodacom data sim on 13 September 2021 the amount of R230 sim no ***. They however continue to deduct the debit order from this date. I keep calling them to find out why they keep taking money from my bank. But they telling me that its cancelled and they will refund my money but its been 8 month and im still waiting. Im fedup now because today when i called they tell me the account is at legal. Why would a cancelled contract be at legal. I must use my money to keep calling vodacom and im running up and down now for 8 months. Im not going to call you again. I want my refund of the R230 for 8 months back into my bank account. I dont care who did what because the voice recordings clearly show that i cancelled this data contract last year September 2021. So dont come and tell me the account is with legal. All the recording will clearing proof who is giving false information. This is my last ref where i was told that my refund will be done within the next 5 days. Ref. *** on 09 may 2022 spoke to keitumetes. Vodacom I'm really disappointed in the manner your customer agent deal with a query. Please contact me.
