I want to know if I can take my old company to small claims court for remaining money on a closed corporate card in my name?

I have transitioned companies. In closing out my affairs at the old company. The credit card that i used for business purposes but was in my name has a credit balance on it of 157.53. The credit card company said that the old company has to send them notification that it is alright to release the funds to me. I have attempted to contact the company a multitude of times to request a call back or email with instructions on how to request the funds over a period of a month or more with no response. So I would like to file a claim in small claims court for the funds, is this a appropriate use of the small claims court and in your opinion would this result in the desired outcome?
