Don't pay these people to file for you, just go to www.fmcsa.dot.gov to file yourself. They send emails, many might I add, with the threatening language and the name of the business is very misleading and confusing which is how they stay in business, I'm sure.
When a business is played by them once they won't do it again, so they will prey on naive business owners just trying to follow the law. The actual application on the government website was easier to fill out than using this service… and it was free. I wish i could get my $150 bucks back the more you know. Shame.
