DSTV Accounts Department Does Not Wor****

Same problem every year! I pay my DSTV annually and every year at the end of March I have a problem. There is no statement or notification of the amount is due. On checking the website I found finally found an amount and paid it. Now a nearly a week later I'm cut off for my account being "Overdue"! Phoned the call centre - took 10 calls to get through - and the agent could not even tell me when my account payment was actually due. Today the website says I owe more than I paid last week! Website has no email address for proof of payments to be sent to. Not holding my breath for the statement I have asked for. Didn't get one last year despite many promises from call centre agents and supervisors.
