Liar. First, there is no Nankai Intermediate People's Court; Second, the court's subpoenas have been served, and there is no telephone notice; Third, if it is not a major criminal case, it will not be tried directly by the intermediate people's court (major cases will be detected by the public security bureau or investigated by the procuratorate, and you can't ask the court to hear them directly). So he must be a liar.
If you have time, I suggest you call the police first, and then cooperate with the police to catch liars, so as to give yourself a bad breath and prevent them from cheating others again.
