Angry ex client

On the 11th of October 2022 I wrote a review about Rain here on hellopeter expressing how disappointment I was with Rain because I had been without connection for more that two weeks without getting any assistance from them eventually I got their attention and just over a month a Technician came through to my house to check the route only to find out it was indeed faulty then he checked on his laptop and realized that I didn't have a service for over a month now and he said he would escalate this matter so that I don't get charged for that whole period. To my surprise I was billed for that period and that's when I called and asked why am I being billed for something that I didn't use they insisted that I had to pay for that bill and I asked them to cancel my subscription and that's when I was told that I can't cancel my subscription because I had an outstanding balance of the very same month that I didn't use their services because my router was not working. I then disconnected their route asked them to come and get their router as I no longer need their services but they carried on billing me and now to my surprise I get an sms saying that I have been handed over for an outstanding amount of over R2000 which I do not understand where it is coming from. I am very angry and disappointed and I will not pay for something that I didn't use. Rain is a #$%& company.
