Why is money still coming off of my account when I have cancelled with your service?

I am thankful that you gave me two payments of R499 as I had requested after having canceled the rain service, however, my bank statement shows that you took a further R99.80 on the first of July. What is this payment for? There has never been any mention of new fees being added to a canceled account. Please reimburse this money into my account. I have given and will continue to give you no permission to take any money from my account. There is a running fee statement of R1200 this makes no sense as I have paid you in full the service rendered while I was in the use of rain however once I canceled I canceled for good with no fees needing to be paid, the router was returned too. Again I don't have any running fees that need to be paid up, and you need to give me the R99.80, then close my name out of your database as I have canceled and am not your customer. Thank you.
