verbal salary contract broken can I be sued if I break non-compete after only 6 weeks of employment?

I moved my family from Florida to South carolina to work for a garage door company in Charlotte, NC. When hired the employer stated I would earn my asking salary of 700+ a week. I was paid far less than that. I was then fired after 6 weeks when I started asking about the money I was supposed to be making. He is now threatening to enforce my non-compete I signed with him.
