Non compliance fee

In my ongoing tug of war with our management company I have possibly spotted a new problem.
In our monthly report dealing witn income and expenses I spotted a fee buried in the Utilities section of the monthly expense. Normally the Utilities payments consist of: Electricty, Gas, Phone/Internet and water/sewer.
This past month a $432.50 fee called a "levied non complainace fee" was added to the list of expenses. In over 20 years this type of fee has never appeared on our income /expense report. It was the first time such a fee was reported. The fee of $432.50 far exceeded the combined total of all the other utility fees combined.
The obvious thing is to ask the management company for an explanation (the BOD Directors/Officers will not repsond to any question). So I have sent 2 emails to the management comapnty asking them what the fee is for and who did we pay it too. Affter two weeks I have heard nothing. They did acknowledge receipt of my email but so far crickets.
Any idea what this fee could be for??

The property manager works at the board's direction, so ultimately your needs may have to b addressed by them. If they're not responding to you, it may be they're researching the issue themselves - ever think about that?

You also say this is the first time you've seen this fee, so this doesn't necessarily mean there's get another conspiracy or something. Perhaps you might contact one of the utility companies and see if it levied any charges for non compliance? If so how does that come about?

Does your HOA use credit cards or maybe ACH payments for certain owners? I wonder if the HOA has failed to abide by some aspect of security required by the credit card industry or ACH. See the discussion of non-compliance fees at:
