DSTV BILLING FIASCO

Two years ago i stopped my service as i got married and my wife had DSTV. We moved and decided that DSTV must be on my name so I went to re-activate my account. In June 2015 on the last day i stopped the service yet due to their incompetence the system drove an account for a month and a half, ran a so called bill of R420. No one in two years informed me of this and never did it reflect on the credit bureau. When i query now they say its linked to insurance, but insurance on what, I never had an account. It gets better, my wife stopped hers last month on the last day and guess what, she gets notified that she owes and they going to list her. what in the hell are they doing?
