Cancelation and Refund

I called in January to close the account and they debit me my final fees in February than All of sudden I'm receiving another debit order I reverse it because I know that my account is closed and on March 17 2022 I get a call saying I have outstanding amount Omg I lost tried calling the call center they told me my account was still active they only canceled it than and I have to pay another R900 for the closing of the account when I query about the first debit order for 512 that went of for closing the account I asked for a refund and they hang up the call on me and not assist me and currently I'm not working that's why I called in early to close the account and one consultant is saying it's my fault very rude and poor service
