If you intended to defraud them when they gave you the money, and had no intention of paying the debt, it could result in a criminal charge. Depending on how long ago this was and what the facts are I doubt there could be a valid criminal charge and stating this is a violation of the law.

Threatening criminal charges for a civil debt? Seek local legal help immediately. You may have a claim against them. If the other party is a debt collector (not the original creditor), you sound like you have a claim for violation of the federal Fair Debt Collection Practices Act. If the other party is out of the country, they are blowing smoke and you cannot get at them.

I had a similar case in Austin recently.
My client was charged with issuance of a bad check (IBC). The charge was in justice of the peace court. It ended up being dismissed. The prosecutor usually won't dismiss until right before trial.
If you gave them truthful and complete information at the time you got the loans, then you have done nothing that could result in criminal charges. The failure to pay as agreed is not criminal but it is a civil matter. I would tell them that you consider their calls and threats to be harassment which in Texas IS a crime, and that any communication with you on the matters must be in writing. Further, you want a full accounting of all loans and payments because they are fraudulently trying to get money on paid accounts.
Although I have answered the question to try to help you, you should consult with a lawyer in your area in person on the matter. In addition, my answer does not establish an attorney-client relationship between us.
