What can homeowners do in NYS if the condo board raises fees based on bogus vendor increases?

Our condo board raised fees for 2025 that were higher than normal in 2 areas. One was an $8000 increase for landscaping, when I asked to see the contract, it turns out there is NO increase for 2025, the current contract was signed in late October 2023 and is good for 2 years. The other area is the insurance which they say is going up $11,000, I have asked to see the proof and so far have not received it. What can we do if that is also a lie? Can we demand they remove or alter the budget and reassess our fees? Thank you!
