This is a scam, THey claim to be a debt collector

Scam trying to get you to send them money for a loan you didn't get.

They sent me an email. I'm not calling them.

Is this really a scam.i got an email from sharon warden saying that they will sue me.the email has my ss number and my employer.can someone pls answer me.

Email is not a legal method of debt validation.  Read up on the FDCPA and learn your rights.  http://www.consumer.ftc.gov/articles/0149-debt-collection

These people sound like scammers who have gotten ahold of your personal information.  Do not give them access to your bank account or pay them a dime until they have validated the alleged debt as outlined in the FDCPA.  Bet they won't be able to properly validate anything.
