Dear Madam/Sir,
I once lived in Pennsylvania for several months nine year ago and left USA. I came back to USA five years ago and have been lived in New Jersey since. Last week I received a debt collection letter from a collection company to acclaim that I owed the phone company three hundred dollars. I was very surprised to have it. I would like to ask you what I should do next? How many years the debt should be invalid? Since I really can not remember if I left the phone for my roommate or stop it when I left, and I can not find my roommate now.
Thank you very much for your help.
James
