Breach of agreement

In February 2015, I made numerous calls to get Onair TV to correct my billing. In March it was rectified but I was informed that they could not do anything about the first debit order. In March, all was well and in April, they went back to debiting the incorrect amount. The service is poor and dis-satisfactory. I have complained and no one has responded. I will now approach the social media outlets to publish the letter from them stating the new terms and their breach thereof.
