Hi Knee,
Welcome to the forums.
Please do not stress yourself to the extent that you fall ill. Ellis Crosby is undergoing legal actions and they are trying to scare people in order to recover the debt. They are out of business and you do not need to pay them anything.
If they are asking you to pay anything, ask them to validate the debt. Samples of debt validation letter have been kept in this forum.
They can't do anything beyond scaring you. Make use of your consumer rights and file your complaints against these harassments at the FTC, BBB and the state attorney general office.
Please do not panic over this issue and I am sure that you will feel stronger after reading related posts about the said company in this forum. You will be able to take the stronger side of yourself and fight back.
Regards
Roxette
