Disregard all the advice you've gotten so far that suggests doing anything other than talking to an attorney.
Considering your circumstances, your attorney will most likely communicate and agree to some sort of settlement. Just comply with all their demands, provide any information they request (such as proof of income), and move past this. I promise that acting like a hard ass, as some seem to suggest, or fighting this on your own will leave you with nothing more than sleepless nights and stress that your mind and body won't appreciate.
It's really easy for people who aren't in your shoes to spell out fairytale dreams of how they'd beat up the serving agent, shit on the attorney and beat the case. Much like all internet bravado, it's left online when reality hits. Just take it seriously, get an attorney, and work things out maturely and professionally.
Post up pics of the letter they left at the door. There is no fucking way some guy came to your door working for the company and left you a letter. Sorry but no one hand delivers mail these days LOL.
The mailman probably left it in front of your door. It is probably a fake letter. Post it up the contact details of the law office that is sueing you so I can check it out.
Either your pulling our leg or they are pulling yours.
Actually, when you're served, the documents must be delivered *to you* physically. In most cases, certified mail won't even suffice. If he's telling the truth in this thread, I assure you, they're real. And no, fenway, do not scan them and post them on this board.
