Rain Month to Month ****

Rain advertise their services as no subscription, month to month service . I did not pay for one month and my services was disconnected for the entire month of September which was fine . Then I paid R595 in October to get services, I got reconnected in October and now in November they tell me I have to pay for September when the both the router and sims were disconnected due no payment .

I called the call Centre to get an explanation , but no one can explain why I have to pay for a service I did not use and why a month to month service now requires you t pay every single month even when they have disconnected the service to that whole month , they still want me to pay for it ?
