Unless you negotiate a new contract or addendum with your PMC, they do NOT have to abide by any requests/demands you make that contradict what's written in the management contract.If they have in fact NOT followed the terms of their contract, then you'll want to send them something in writing pointing out the specific language in their contract that they violated and ask what they plan to do about it.If they fail to correct or address the issues, then you'll want to start looking for a new PMC.
