Your situation sounds like a case of identity theft. If the loan company/collection agency calls back, ask them to "cease and desist" all further phone calls and only communicate with you in writing. Further, you should ask them to provide you with verification showing that you, in fact, signed for and received the loan.
Second, if it is a collection agency that is calling you, they likely have committed an FDCPA violation for threatening you with a criminal charge. Other violations may have occurred as well and you may have a claim against the company for those violations. Try to find a consumer attorney in your area to evaluate your claims if you want to proceed further.
Lastly, if you do receive a summons, do not wait to contact an attorney. You have 28 days to respond to that summons or risk being in default. Again, you probably want to speak with a consumer attorney in your area.
Do not give out any info.
