If they call, it may be to confirm whether the medical examiner has received the medical examination results, or to remind them to make a follow-up appointment or consultation. If you receive this call, you can politely ask the identity and intention of the other party first, and then respond accordingly according to the situation.
Of course, if you have any doubts or uncertainties about each other's identity and intentions, you'd better be careful not to disclose personal information or make promises easily. If necessary, you can consult or complain to the local consumer protection agency or relevant regulatory authorities.
