Is there a big chance of winning the case of refusing to pay the property fee because of the leakage of the external wall?

Because the property service is persistent, long-term, comprehensive and professional, although there are service defects, it is not enough to constitute a legitimate reason for the owner to refuse to pay the property fee, so the probability is not great.

Owners have the right to put forward reasonable suggestions and opinions on the lack of property services, and property services should be improved. The defendant claims to discount or reduce the property fee on the agreed payment standard, but the evidence it provides can only reflect the unsatisfactory part of the plaintiff's service, which is not enough to prove that the plaintiff's property management service violated the main obligations stipulated in the contract.
