Sent out my first C & D letter to National Service Bureau and Magnum today, thanks to the unbelievable amount of information on this site. After the payments I've already made to NSB, it turns out I'm only $10 shy of the principle amount, instead of the additional $2100 they are trying to get from me. Hopefully I get as lucky as some of you are reporting on here.
One down, two to go and I'll be able to answer my phone without checking the caller ID first!!
Thanks to everyone on here for all the information and resources on handling these scam artists.
