Credit card mess with condo association

I opened up a credit card in the Condo Association's name in order to pay the bills until the assessement could be done or until fees were raised. It got out of hand so I gave it to another Property Management Company to take over. They do not want to take over the credit card which is in the Condo Association name and backed with my social security number. They said they will pay it but they want me to pay the $2,000 in interest since the condo board did not know I took it out. What do you think?
