Decoder payment plan

I recently app**** for car finance and was declined,because of a decoder payment plan (ddp) that is on my name that was found on a credit bureau which I knew absolutely nothing about!.. I currently have a dstv internet package and have no outstanding balance with dstv.. This is ridiculous! And apparently I am paying R69 a month towards a R1600 debt! (which is absurd).. This matter needs to be resolved. I have spoken to multiple agents to find out how to go about sorting this issue out but they all tell me that there is isn't any outstanding balance on my name?!.. If that's the case then why is my ID number linked to an outstanding amount that was handed over to a credit bureau?! This is an absolutely ridiculous situation that needs to be rectified ASAP! I just want this issue to be resolved, I even asked how can I settle the amount and pay it in full just to have this matter dealt with even though it's not my fault but I have received no assistance nor any feedback.
