Hi, I was being harrassed by Encore collection agency over a debt that is a few years old. I wrote them and asked for validation and never heard back from them, this was several months ago. NOWI am hearing from an altogether different agency. Got the letters in today mail. Why didn't the other agency just send the validation when I asked for it? could this mean that there might not be any? This new agency is called encore ---if anyone knows anything about these people, please share. SO...do I respond right now with a validation letter to them?
