Angry customer and disappointed customer

I have been using rain for some time, I decided to get the mweb line.i called in advance before the subscription date.i canceled. Im not behind in my payment.They also sent me an Sms saying the sim was canceled. I haven't used the service in two months. I was debited twice R529 this morning, The device "router" was to be collected on last week they rescheduled to Tuesday. Im not certain what is going on here.My understanding of month to month subscription means the service should be suspended when you haven't paid or when they have canceled the sim card.
