Midland funding LLC -- pain in the butt

i received a summon from them last week , cohen and slamowitz is their attorney. they bought the debt from citibank and trying to get the money from me. in the mean time, they sent me settlement letters to settle my debt for more than what they stated on the summon, offer me 50% discount on the original debt, and also offer me to pay the debt off while i get my tax refund..

i answered the summon last week and arranged a court date on May. i ignored all of their mails.


today i received another law firm Rubin & Rothman, representing Midland funding. but this time is even funnier, the letter looks bogus / scam. because it got nothing more than a number that the lawyer said i owe Midland, and no account number for any credit card numbers I ever opened or owe. just a file no for the law firm.

in the last paragrah, it said no attorney with this firm has personally reviewed the particular circumstances of my account..

my question is.. can i file a complaint of this fxxker? where should i file these complaint if i can. what the hell is their problems to send me dunning letter asking for money they don't even know about? they even ask me valid the debt, and list all the payment methods they accept. should i just wait till they get the summon? report them as scam?

i can't keep on sending certified mail to valid these so called debts . everytime they change collection agency, i have to spend $6 for each DV and knowing they won't send me anything back anyway.

any idea, thanks
