Credit Collection Services CCS lying about previoous phone calls, refusing to refund in timely manner Newton Massachusetts

I had an account sent to CCS for collection. This was not sent because I didn't take responsibility for the debt, but because i simply coud not pay it (Quest Labs). I received a statement from CCS telling me what my payment would be. I thought I could manage it, but was not able to. I called them as soon as i realized i could not pay the specified amount, and negotiated a lower figure. I was told the original amount would not be processed. Much to my surprise and chagrin (maybe should not too surprised after all), when I checked my bank account shortly after the due date, i found they had taken a payment out that i made over the phone, AND the amount I had originally said I couldn't pay. I was furious.

I called them and was told that it could take up to 30 days to get the refund. Since I had to pay my rent, I faxed the document in question to their fax number that i had been given. I was told they had received the fax on the same day i sent it. I was also told the refund was already in process, and I would have the refund by December 11. It did not appear in my account today. So I called them, and they denied the phone calls that i had made, and also told me that they never received the fax. I was also told they would BEGIN processing my refund today, the 11th, but it would take 30 days.

I signed a promissory note for my landlord with today's date on it, since I had been told I would have the money today. I could face eviction for not paying my whole rent (I paid as much as I could, since I was told what turned out to be lies.) I also told them when i was first discussing this matter that i expected to have them also pay my late fee (A girl can dream, can't she). They were not impressed. Bottom line: They lied to me, hid communicartion between us, and are taking more time than i was told it would take-after faxing the voucher in question to them. I need to find out to whom I can go about this company.
