told me if I make pmt arrangments that they would not persue a lawsuit against us but to wait for a letter in mail to sign I believe to be an "acknowledge" letter. two weeks passed....no letter. Everytime I called to follow up about the letter, I was sent to voicemails with no returned calls so I became suspicious about the collections co. This pass Monday I was served with a summons and complaint! Mind you, I NEVER received documentation prior to this. I filed an answer and my question is, should i ALSO send a debt validation request letter since we are unsure of the amount we owe, and if the statute of limitations applies? and if this so called law firm is allowed to collect in my state? will the debt validation provide me with last pmt date to see if sol applies?
