The store refused to pay the property fee because the drain pipe was blocked by grease?

You can't. Property fees need to be paid, but property losses caused to the owners can claim property compensation, according to:

1. If the property management company fails to perform its contractual obligations, causing personal and property damage to the owner, it shall bear the corresponding liability for compensation.

2. If the realty service enterprise has fulfilled the realty service contract and there is no fault in management, the owner cannot refuse to pay the realty service fee accordingly.

3. If the owner's personal and property damage is caused by the tort of a third party, it shall bear corresponding supplementary liability for compensation according to the fault degree of the property company.
