Bad customer service

I am upset and now at my wits end with the level of service multichoice is giving me . I get different answers from cinsul8when I asked about my suddenly high subscription fee that I am supposed to.pay . I have been trying to fix this since Sunday. I was told it was a system glitch. Then I was told i was charged for August month. I was also told nonpayment which I find strange as I have been.paying the balance on the account on time. I need to know why they ran specials and then come back to claim the money from customers? This is bad customer service and I am even considering canceling my account .
