<<Sigh>>
Pitomate,
Not to belittle your experiences; however, I'm pretty certain there is more to your story than we're getting.
If these Bozo's were going to get you for "bad checks" you would already be "got"! They're not going to call and warn you they are going to sick the po-po on you. "Yes Mr. Debtor, the police are on their way, so you wait right there!"
Right
These dumb-@$$es are violating the fdcpa by even threatening to have you arrested. Illegal Mediation Practice is probably collecting on a Pay-Day Loan, you cannot be arrested for being in debt and unable to pay; it is a civil matter and not a legal matter. You can, however, probably be arrested for writing bad checks; however, I would ask Illegal Mediation Practice to fax, or mail, copies of those checks to you so you can see them. I'd be willing to bet they would never materialize because they probably don't exist.
LMP is using every illegal tactic to get people to pay them money, and I'm certain it works for them most of the time. I had my own experience with LMP and was threatened with the Police (among other things), months later and I'm still waiting for them. I even got an attorney and was ready to sue them for multiple violations of the FDCPA. Guess what?!? They settled out of court. They probably didn't want their sorry @$$es dragged into court as they would have probably had to pay a lot more when they lost!
They are idiots and don't ever let them intimidate you. Learn, from this site and these forums, about the FDCPA and your rights. Send LMP a debt validation and cease and desist letter. I would be willing to bet the farm you will never receive anything in writing in response to your letter. That's a violation of the FDCPA right there; one to get you started. Collect them, share them with your friends, and when you have enough collected: sue the poop out of them!
I sent the DV and C&D letter to them and, months later, I'm still waiting for a written response.
I just wish I could afford to take out an advertisement on prime-time network TV and warn people about these bottom-feeding @$$-clowns! They really irritate me.
