Excel Aquisitions help Needed Urgently

Hello All

I hope you guys can help me :)

In 1998; I had an account with providian bank; I paid the account in 1999. When I reviwed my credit report In 2001 I found them on my account I contacted them and they stated they did not have an account for me on file. I requested if they can send it to me in writting and they advised me that because they had not account on file for me they could not supply a letter. At this time Colorado Capital for providian was stated on my credit file. I disputed it with the credit agencies and it was removed.

On 1/13/07; I received a letter from excel Aquisitions stating there was a balance of 4000.00+ owed on this account. The collection letter had no license number but advised I had 30 days to respond. On 1/16/07; the added the account to my credit file and reaged the account as of dec06. I attempted to call them and get a physical address and was advised they only had a PO Box address; I then decided to see if they were legally allowed to collect in the state of NY and long behold they are not. I received correspondence from Consumers affairs with there findings. I also placed a complaint with the Better Business Bureau stating they would not provide an address and furthermore they did adhere to there time limit of 30 days. I received an update from the BBB witht he company stating that I am liar and that they are forwardeding the case to a NY law Cohen & slamowitz; they also said in regular cases they would wait until they received the paper work but in my case since I admitted to having a paid off account with providian they will send it immediately for remedy.

Please note I sent a certified letter on 1/19/07 and they are in receipt of my request for validation as well as anyother information. I have done some research on both Excel and this lawyers office and they both have a stream of open cases on them for collection tactics and activity.

I have called the civil court and was advised that there was nothing I can do until they file suit but because I have been through this with Mel Harris I know they can lie and say I was served and receive a judgement for a hold on my bank accounts.

Please advise what my next step should be

Thanks

UPDATE
I RECEIVED A LETTER TODAY FROM EXCEL ACQUISITIONS. IN THE LETTER IT ONLY STATES THAT THE ACCOUNT WITH PROVIDIAN BANK NOTHING MORE AND I SHOULD CALL THEM. NO LICENSE NUMBER OR ANY OTHER INFORMATION I REQUESTED. WHAT DO YOU GUYS THINK I SHOULD DO NEXT BECAUSE I CALLED THE COURTS AND THEY SAID TO JUST WAIT THIS IS SO FRUSTRATING :(
