Rain is Robbing subscibers

Have been using rain for some years. I recently changed to the new 101 square router and all of a sudden promise to pay doesn't work. Promise to pay is when you pay your subscription in parts. Now I have to make full payments in advance for internet. Fast forward to 15 Jan they disconnected me because new bill is due. Which i dont have a problem with because i haven't paid. Fast forward 29 Jan 2026 and the double the subscription, i now owe for 2 months, for services not received and services not yet received? My payment date is 15 of the month. I want yo cancel. They say i cant, i must pay R1298 first otherwise every month they will add another subscription amount FOR SERVICES NOT RECEIVED. I AM CURRENTLY USING CELLC DATA. IN contract law this should be *******. We must create a class action against Rain. The call center is answered by people in Asia. I got call ref ***4
