Onair customer service nowhere

I have a contract with Onair for more than a year. Payments are debited from my account via a debit order every month. Early April 2018 I app**** for credit, only to be informed that I do not qualify for this due to Onair having blacklisted me at the credit bureau for R199 outstanding. I queried this with them, as I have never missed a payment. They confirmed this with me, and sent me a letter to this effect on the 10 April 2018 after once again following up with them. On 7 May 2018 I then again app**** for credit and once again was declined as the ONair account still has not been cleared at the Credit Bureau.

Onair's inability to correct their mistakes has severe consequences for their customers.
