It is all bull. They try to get around the laws by saying they are not a debt collector. Apparently it works pretty well in most states, Massachusetts for one it does. The only way you can get them on that is if you actually got something in the mail from CACH LLC, with their name on it attempting to collect a debt. That only works for licensing in Massachusetts.
As far as the FDCPA, it does not matter, debt collector, debt buyer, attorney collecting a debt, they are all the same and all fall under the FDCPA, unless it is the original creditor collecting a defaulted debt in their own name.
Now is the time to build up a defense. You need to go over EVERYTHING. If they say that the account was opened in 1999 and gave you a credit card agreement from 2000, make note of it. Label everything as exibit "A" and so on. This way when you go to trial, you can present it as evidence to the judge. This way you can present your side, objections,.......
You really do need to study up on this stuff if it does go to trial. If you fail to make objections at the right time, it could cost you the whole case. If you have to, go to a court house and watch a debt collection case at trial to see what goes down.
An affidavit of debt is hearsay and can't be used unless that person is present at the trial. The credit card agreement is good for toilet paper, who's to say they don't photocopy that for everyone they sue? it has no ties between you and the original creditor without a signature on it.
Unless the statements are from the OC then they are not valid in court. Anyone can make one up. usually they are probably microfich (sp)??? Check the account number on the statements. If it is not the account number they are suing you for, then it is no good.
