don't care attitude

I called in to complain about their consultants calling me but continue chatting to their colleagues in the background. I refused to pay for a call to me seeing that I did not chat to anyone. after numerous calls to their collections department I still have no feedback and this is going on since may this year. I do not have a problem in settling the account in full , but based on principal I refuse to pay this account until such time that they sort this out. I received an e-mail from an Attorney that they handed the account over to despite the fact that I have a dispute with them. It seem that this company does not have an ounce of professional courtesy. I have suggested that they send me a letter of summons to appear in court should they wish to continue in manner. I have consulted with my attorney in the interim.
