[CONDO][PA] Breaking up contract with management company, who's responsible for contracts?

We have notified our current management company of contract termination and there is still money owed to vendors such as Trash and few others.

One of the main reasons we terminated is because they were incompetent and put us into bad contracts, amongst other issues.

We as a board never signed a contract with anyone, it was always the management company. Such as insurance, trash or other vendors. When we terminate contracts with the management company, are they the ones on the hook for any terminations?

We have never as a board signed any vendor contracts and it just befell on me that there are no signatures from any of us on any documents. Even if the management company worked as an agent for the board, shouldnt the final signing authority rest with the HOA Board?

Were in a bad spot with some vendor contracts due to overages which we were not aware of when we discussed said contracts, and the managing company might try to draft something legally where they are not liable - which is what I am trying to determine.
