Nightmare experience

I am at my wit's end with Rain. I have tried several times to communicate with Rain via their support number and have not had any success. The last time I called on 25 November 2023, I ran out of airtime holding the line for a consultant. I had requested them to collect their device as I was not getting any joy from Rain. What they are continuously doing is to bill me for services I have not used. I was made to understand that this is a month to month service, but then I found myself being held hostage where services would be suspended by the 20th of the month and I would be forced to find a way to make payment for a prepaid, month-to-month service, simply because I desperately needed to stay connected to the internet. I don't know how else to contact them. Even today, 25 December 2023, I've been on their telephone line *** and no one is taking the call. At the end of this line there is no helpful agent ready to assist.
