Can Multichoice do this to someone?!? They black listed me when i paid!

<p>So here is the my story. I cut my DSTV last year 2015, and i was charged around R300 odd for this. I said i was not going to pay due to me not having a service and there is no reason as to why i had to pay this amount(The service was not longer avaliable). Subject to say, the owing R300 was paid last year as well which i thought of as a donation to Multichoice, because i did not want anything on my name which reflected as unpaid. A few months later as in now, i want to go and finance a car, and they tell me Mutlichoice has blacklisted me with Experian!!! Now currently i am black listed, i can't buy a car, and everytime i call multichoice i get a new reference number and nothing is happening! </p> <p>How can you black list me when i paid! how can you not clear my name after all this time! and *** is going on?????</p> <p>Reference numbers: ***; ***1-i20; ***</p>
