Is it legal for private WeChat to collect property fees?

My property fees in the past three years have been directly transferred from the property company to the private WeChat for collection. It stands to reason that it is illegal for private WeChat to collect property fees. However, it is not illegal or necessarily legal, because the collection of property fees is only stipulated by laws and regulations at present, and there is no legal provision, so there is no question of whether the collection of property fees is legal or illegal. Only compliance, no compliance.
