Multichoice forcing me to pay for service I dont need anymore

My billing cycle as per Multichoice ends on the 1st of each month, which was a Sunday holiday, Monday the 2nd was a holiday and I informed them that i didnt need the services anymore. They only responded to me 24hrs later informing me that they dont services in between the billing cycle, but only on the 1st. 1.Where on my contract with them has that ever been communicated to me that services can only be disconnected only on the 1st? 2. Am I NOW FORCED to pay for a service which I definitely beyond reasonable doubt am not using at this particular juncture 3. What type of a stupid IT System are they using which does not allow any other activities in the system between the billingcycle, or its the lazy employee syndrome? 4. Does that mean that if I want themto upgrade from mini bouquet to full bouquet they will refuse, why? 5. This is a way of manipulating us and robbing us of our hard earned money, m******xm
