Lawyer/collection agency is trying to collect an alleged debt that I do not owe. I received a letter from another Law firm saying that they are collecting a debt for XXXX XXXX. An alleged debt that another law firm called Bowman, Heintz , Boscia & Vician were attempting to collect a few months ago. See case number XXXX of my previous complaint. Seems like the debt was sold to this new law firm called Blatt, Hasenmiller, Leibsker & Moore but this new firm or previous firm will not provide me any evidence that they purchased the debt from the previous law firm and they are now the new owners of this alleged debt. I asked for a copy of an agreement that has my signature and to validate the debt by showing a signed contract with my name that this alleged debt is mine. They have failed to provide me any evidence that they have the right to collect or that I even owe this debt. They provided me a copy of a judgment from the courts but anyone can get a copy of a judgment from public records. Having a copy of a judgement does n't mean that you own the debt and by just saying that the info has been validated does n't mean that it is true. This is all hearsay until we see some type of evidence that I truly owe this alleged debt. I have asked time and time again from the previous law firm and this current law firm to provide me with evidence that this alleged debt is mine. No one has produced a contract or an agreement with my name on it and they are just passing this info around to try to collect money from me. I do not owe XXXX XXXX anything, I do not owe this law firm anything. Not even sure how they come up with the amount they say I owe. I have never signed an agreement with XXXX XXXX and I do not have any contracts or an account with XXXX XXXX. The law firm is just a collection agency that is trying to collect free money. It seems thought that the first law firm gave up because they could not prove that I owe the alleged debt, so they past the case to another law firm which I found out the new firm is in the same building as the first law firm. XXXX XXXX, XXXX, IN XXXX. What was their consideration of the payment? what proof they own the debt now? Was this assigned by XXXX XXXX, if so why did XXXX XXXX change lawyers when they already had someone trying to collect the alleged debt from me. This law firm is just another collection agency that is trying to get easy money by sending letters to consumers saying that they owe debt but ca n't proof any of it. This should be against the law. They should be able to provide something showing that the alleged debt belongs to whom. If I said that the alleged debt was paid in full, they would want some time of evidence that shows the debt was paid. I should have the same consideration. I ca n't just write that the alleged debt was paid, I would have to show it was by having a copy of the check, receipt or something in writing that it was paid. The agencies need to show something as well and stop sending letters trying to scare consumers to paying because they say we owe. Please view the letter that was sent to me as well as the letter that I sent for them to validate the debt or show any proof that I owe this debt attached to the complaint. Also see exhibits XXXX, XXXX, and XXXX attached, showing what is happening across this country with consumers and what FDCPA has been violated.
