Am I able to sue a LLC in small claims court for $620?

My daughter was playing softball and the team was unexpectedly disbanded. We have paid over $620 for tournaments, games, practice, equipment, uniforms and college recruiting help. First tournaments were cancelled, then games started to get canceled then practices then no more team. Also the only equipment or uniforms we received was a practice jersey. Per the contract if a player leaves we forfeit all monies so I contacted the owner and asked if we would get our money back since they chose to cancel team and she stated yes. This was in October and I received numerous reasons why she handnt paid yet and now in the last month she has not answered any emails. I am at a loss of what to do.
