Rain Bad Service

When I signed on I was informed that with Rain it is a month to month account and if I was unable to pay for a month I could ski their service that month and then continue the next. The one month I was unable to pay. Rain attempted daily to take money out of my empty account causing cots to my bank account for fees on the rejecting of payment. I eventually managed to contact them and asked them to stop this. The were not nice about it and again attempted to get money out of my account costing me more money. I then instructed them to close my account for I would no longer use their service. I also told them I would settle my account when i am able. In 2023 I got a notification of an outstanding amount and I paid it in full. As far as i was concerned I no longer had any dealings with Rain. Just for safety I logged onto my account and it showed me owing them just over R14. I did not owe them anything. I tried various times to call and email but could not contact them in any way. Eventually I managed to log an exception on the rain website Reference Number: ***3 with the topic cancelation. They never even responded to this. Since January 2024 they have constantly phoned me telling me I owe them more and more money. Every single time I have told them I am no longer using their service and owe them nothing. They have since called me 7 times and every time I give them the same information. It is impossible to contact them via email or on the telephone. I am now considering taking legal steps against them for harassment. Even this very day they called me again. This has to stop now.
