ConAir TV is destroying people's lives!

I cancelled my contract with OnAir TV within the cooling off period and paid a requested R350 collection fee for their Dstv Explora decoder, which I was led to believe was different to the Dstv Explora decoder I was using. I paid the fee within the 30 days I was given, but OnAir TV proceeded to create profiles on various credit bureaus, reporting that I have been defaulting on my payments. The company also created a debit order on my personal bank account even after I have made several attempts to address the matter with them, requesting that they investigate my queries and clear my name. I am currently looking for legal help to intervene because this is creating a negetive picture on my credit history and affecting my credit score.
