Contract help

[schoolbound]

I recently got married a couple of weeks ago. When we signed the contract it stated, "There is one working bathroom facility provided indoors,... It is the renter's responsibility to order portable bathrooms at their expense if they choose to." They were suppose to build more bathrooms by the time the wedding would come around, one day before the wedding we found out that the bathrooms were not built. They told us we must rent and pay for it. We simply told them, it's too late and we are not paying because we were under the impression they would be finished. Flash forward to the day of the wedding and there are two portable bathrooms out there. That was fine, but I told the owner directly that we are not paying for it because we did not order it. The California Department of Health requires one working bathroom facility for an event, which clearly in the contract states that they have it. While I was on my honeymoon they called my dad and said that it was against the Health Department and that he is obligated to pay for the bathrooms. My dad paid them 1,000 for it. Now, I know that owner just tricked my dad into paying him for the bathrooms. The law says you just need one, and the contract says there is one.

Is there anything I can do to recover that money? They lied to my dad and made it sound like he had no choice. I would really appreciate some help on this. Thanks
