DID NOT DEACTIVATE ACCOUNT AND DEBITED ME FOR UNUSED DATA

I requested to deactivate my Rain account on 25 March 2022 , after requesting deactivation I got a call from an agent who asked me if I did request to cancel the sim card , I agreed & advised my parents installed Fibre so I didn't need 5g any longer , after which the agent advised me that I will be billed for the month of March data usage , I agreed as well and was advised the router would be collected within a few days . I was under the impression that my account was in the process of being deactivated ... No one contacted me about collecting the router. I tried contacting Rain several times within the month of March and I could get through to Sales but never Support . I left it , but on the 02 May 2022 I was debited R 499.00 for data which I have not used!!!!! This has really upset me because I tried again to contact Rain but was unsuccessful , I sent an email and got a response to try logging a ticket and then an agent will contact me . If I had no money in my account I would be told that I'm in arrears for something that was supposed to have been cancelled by Rain. I logged into My Rain account to see a green tick next to the 5g option and below that says next billing 1 June 2022 . I still have the router in the box unused since 25 March 2022 . Please could anyone assist as I have been a Loyal Paying customer and to receive treatment like this is DISAPPOINTING!!!! : (
