Is the legal reminder service of Jiufu local law firm reliable?

Not reliable.

Jiufu issued the Notice of Legal Reminder Service of Law Firm, requiring the lender to choose between "replacing territorial claims and legal reminder service" and "self-collection" within 14 days.

If you don't "voluntarily cancel", you will choose "substitute creditor's rights and demand notice according to law" by default.

This notice is nothing more than a plan of Jiufu, and it is an obvious illegal act in obviously unfair! Serious violation of Article 4 of the Civil Law, civil subjects have equal legal status in civil activities.
