Debits not received yet continued billing me

Good day, the current DSTV acc was in my spouses name. payment was made via debit monthly. When the acc was suspended. I made an enquiry this week to reconnect the acc on my name only to be told we are in arrears of R15569.25. My frustration is: The fault lies here with DSTV for not disconnecting the services after 3rd premium was not received! There was no correspondence ie calls, posts, emails to notify the account holder of the outstanding account. They ran up the bill despite payments not received now refuse to explain themselves? I wish to resolve this but their customer service sucks as they don't acknowledge their error.
