RAIN IS BEHAVING LIKE A ****

I have a Rain router in my house. My understanding was that if you don't pay, you don't get services, not you incur arrears. I have been pleading with Rain to cancel my subscription without any success. It's a subscription, not a contract. They are now accessing my bank account on a daily basis hoping to get their so-called subscribe fees. This is affecting my account as every time they find nothing, charges are added to my account. One of my FNB accounts has since been closed due to overdraft caused by Rain. I am appealing to authorities in the communication controlling bodies for help. This is frustrating and affecting my credit worthiness. Why can't Rain stick to the date agreed to when one subscribed to their services. They are so desperate to keep subscribers that they would go all the way to **** them. This is a ****. How can you check on one's account on a daily basis.
