What legal recourse can I take to get a credit card in my name paid off by members of an LLC that I have withdrawn from and they refuse to pay?

I was part of an LLC set up in Wyoming but live in a different state while other members lived in a totally different state. I withdrew from the LLC but kept my stock shares until a credit card in my name for the LLC was paid by remaining members. They now refuse to pay or respond to my calls or emails. They also owe me other money but I would be happy to just get the credit card paid, which was the agreement when I left.
