The problem of asking me for property fees is that from the beginning of the year to the end of the year, I have never seen these people suddenly come to me to pay property fees.

There should be terms of an agreement or contract. If there is no regulation, it is estimated that you and other owners will unite. Who invited the property? If it is invited by the developers themselves, it still depends on whether the owners' committee should be established. Everyone must safeguard his own interests. Moreover, property management personnel generally wear tooling or have certificates. If you don't trust, you'd better hand it in to the management office.
