I think they are trying to sue me, and I want to get some information before sending my debt validation letter. After a lot of reading, it seems that they are incapable of properly validating debts. I've also read of a lot of people saying when they sent the debt validation letter, they got no response except a process server at their door. Can they even do that? If they've already started the process for suing me, is it too late to go for a debt validation? I only started receiving calls (which I haven't answered) recently, and only for me to call back to "verify my address for an important legal document". I have no idea what to do. Someone help. Please.
