SUBSCRIPTION INCREASE

I RECEIVED A SMS NOTIFYING ME OF A SUBSCRIPTION INCREASE ON AL MY SUBSCRIPTIONS. I HAVE SIGNED A 24 MONTH CONTRACT WHICH WAS ADVERTISED AS A SPECIFIC RATE FOR THE 24 MONTHS, NOW THEY WANT TO INCREASE IT. THIS IS NOT FAIR. I PHONED THEM ABOUT THIS INFORMING ME IT IS LAW FULL AND THAT IT IS ALSO ON THE CONTRACT AGREEMENT. FIRST OF ALL THE AD WAS MISLEADING AND THEY ARE BREAKING CONTRACT. I ASKED THEM WHERE CAN A PLACE A COMPLAINT JUST TO BE TOLD THERE IS NOWHERE WERE A COMPLAINT CAN BE LAID ABOUT THIS. HOW MANY PEOPLE ARE THEY GONNA BULLY WITH THIS.
