Rain is ***** it makes unthourized transaction

Rain is *****. I was using Rain internet since 2022, last year I could not afford to keep using it as I had no money, so in September I contacted support that I want to disconnect their services, I have always skipped a month and paid my monthly on the month that I afford which gave me the good impression of prepaid. In February as my things were starting to get better I logged in to pay, to my surprise I had a total amount of R3500 each month I had no connection they kept billing me, I contacted support that they review since they disconnect once you dont make payment and I told them if they can't remove the billing they must collect their router, I just received a message that I will be contacted, 2 weeks later 4 unauthorized transactions of R1046, R529, 529, 529 went off at 4 am from my account. I went to their offices I was only told they can only refund me one R529 with credit, since there was a here and there connection the times I was disconnected.The 2600 they took is my rent money, how can a legit business to a unauthorized transactions? What the point of prepaid then where is the flexibility? That's the reason I chose Rain with no reliable connection so that I can use when I afford. I am so disay. I would warn everyone to never trust rain they are not prepaid and the take payments without being authorized. I feel ****** and this month I will be short rent, internet is a luxury as customers we should be afforded the ability to opt out. Please anyone help I need the money.
