Is it a liar to call Tik Tok's people to promote the year 2000?

Yes Because it is impossible for Tik Tok to verify the identity of the other party by phone, and there is no security guarantee, not to mention there are many online scammers, so someone in Tik Tok called and said that promoting the year 2000 was a liar. Promotion is to promote products and services in the form of advertisements, and finally achieve brand effect or deal.
