Our HOA switched from a good property mgt company to PMP. It appears this was a big mistake. I received a crazy threatening letter from PMP. It made no sense so I asked them to come out here and show what on earth they are talking about. The worst thing is they ignored my request. When I was HOA president our management company was excellent. I did get a form letter that said there is no need to contact PMP when the violation is addressed because the next inspection would show the fix. I thought great, PMP wasting my time is over. But, no, I get a more threatening letter telling me to appear before the HOA board. Included on the letter is a photo of someone else's house. TOTAL INCOMPETENCE.
I request a call from the head of PMP ASAP to resolve this issue. My house attached. WHAT IS THE PROBLEM?
