Disgusting telemarketer badgering me as a small business, trying to sell me a $4000 package that "guarantees" that they will get me in the GSA Schedule.  Then, they say they can't guarantee it, or your money back if they don't deliver.  If you really want a guarantee, they will sell you an ongoing package for $17,000 for the first 6 months, but again, they will not really guarantee performance or your money back.  

I wanted to barf while talking to the disgusting, fat, uneducated, uncaring, uninformed telemarketer.  Rude and useless.  I could almost smell the burp she let out in the middle of the disgusting conversation.

This is a shady scam.
