Poor service

As I am writing this I am very irritated, and disappointed by the services I have received from dstv... I made double payment on the 18th of February of R400 then on the 19th of February I payed again R445, I sent both proof of payments on email, then I received a response saying they have been allocated... My payment date is on the 15th of each month... According to my calculations my next payment was supposed to be on the 15th April but to my surprise my dstv has been switched off.
