For the last few months we have fallen behind in our bills (medical and lost jobs) and even though we tried to negotiate with American Express, they sent our account to the "famous" NCO.
From what I have read, they do not seem to be the nicest people to deal with. They call day and night, they are rude, and totally unprofessional. A couple of months ago my husband finally talked to a nice guy that gave him a break and allowed us to make $200 payments every 15th of the month. Well, that just lasted 2 months, and now, they are back at calling asking for their payments.
