Empty promises meets poor service

Cancelled Rain about 3 months ago. I paid the final installment for cancelation to take place. This month I started getting sms's that Rain will deduct my account for Payment. I emailed Rain customer care and they assured me that the account was cancelled. Rain wil not deduct. Now on the morning on 23rd of December 2021. I get the sms that Rain deducted... I can reverse the payment from my bank but have to pay R80 fee on my cost. Rain If I do it on my cost we will meet in a court for this. I will put in a claim. I expect a refund within the next 48 hours.
