Bad service rendered by Rain 5g Wifi

I had taken their service but is not giving me any joy. As from October I was calling them about the internet not getting it. They deducted few rands and November 2022 same story. When calling the phone takes more of your airtime I bought R110 several times trying to communicate with them but still no joy. I bought data for my family even though I paid R529. I canceled it in December 2022 but still they went into my account to deduct money without any service rendered. I am so devastated because I asked them to come and collect their router and sim card but still no response but they can go into my account as they wish to take my money without approval.
