VERY UNHAPPY CUSTOMER!!!

I am a very unhappy and unsatisfied customer of Dstv for past 30 years I have been a loyal customer paying my account subscription on time every month without fail with this said I am even an ex employee of Multichoice and know exactly how their processes works. For the past month since the first week of September my subscription has been deactivated every week with no explanation when I do call the customer service call center they are very unhelpful and very rude I always ask for the manager on duty to please look at my complaint and take it further as this is something that I have never experienced. I do have price lock and no where in the adverti*****t or no one from dstv every called me to explain that after price lock has expired that the installment that I have been paying will change. I have signed a debit order arrangement with them and it is NOT MY fault as a customer that they don't debit the right amount as agreed upon however as a customer I must suffer the consequences of their stupidity and poor quality of delivering a service to the community.
