Debiting my card even after cancellation

Rain keeps on debiting my card after cancellation. I put in a request to cancel my rain sim card a week before the end of July they said on their website that an agent will contact me. A day passed and indeed an agent did contact me to ask what was the reason for my cancellation I then stated that I can no longer afford it and asked her to cancel it by the 1st of August and indeed it was cancelled on the 1st of August. As time went by they started deducting R3,00 from my account daily from the 1st of October until the 15th of October, it stated that it was a recurring failure to pay. As I thought the worst was over on the 25th of October they deducted R250,00 from my bank account even after my cancellation. I don't know how I can get my money back because I cannot login the rain website. How can I get help or get my money back because I cancelled it due to not having enough money to afford it.
