It is very likely that the customs collection VAT payment form you got is altered or forged.

If there is no real business, it is suggested to stop here and eliminate all vouchers and records related to this business, otherwise it will bring you trouble.

If there is real business, but you didn't declare the import yourself, consult your agent and ask him to give you an answer and explanation. Don't let it go easily. People should be honest.

If there is a real business, and you personally declare the import, then directly consult the customs who declare the import. How can this happen?
