Alliance One Collection Rip Off, horrible customer service Seattle,king county court, Wash ington

I had a traffic ticket a couple of years ago that went to collections (allianceone) and they are the worst people ever! my original citation was 1350.00 and this was 2 years ago, since then it went up to 3700.00 with no explanation of interest accrued and the original amount of the ticket 

I initally had a payment plan set up with alliance one and had lost my job so I contacted alliance one to change my payment amounts and they refused to assist me, so at that time I informed them that I would not be able to send in the whole payment so the rep informed me they will accept the payment. well a month later I receive a letter in the mail from the dept of licensing stating my drivers license will be suspended, now I have a handicap child and a elderly family member I take care of so not being able to drive is not an option so I contacted alliance one whom in turn told be I can't start a payment plan without putting 50% down and they refused to provide me with a detailed record of payments I made and interest my account gained while in collections so I asked to speak to a supervisor and she was no help at all so now I am taking the chance of driving without a license and wondering how I would be able to come up with 1500 dollars

I do not understand how these people sleep at night and do not understand why I am not able to obtain info on my account and isn't there a limit to the amount of interest they can charge? I do not think that it is right that they can suspend your license for that and it's not like I am not making any efforts to resolve this matter. don't I have any rights as a consumer? help anyone???
