The government invited tenders for the introduction of real estate and borrowed capital. Can the property charge the owner again?

If the government invites tenders to introduce the property and borrows capital, the property can charge the owners again. The owners' committee did not sign a written property service contract with the property company, and the owners actually accepted the property service. The owner shall pay the corresponding fees to the property management company according to the actual service price as compensation for the services provided. Therefore, the owner can't refuse to pay the property fee without signing a property contract or the property company doesn't provide qualification certificate.
