Someone else made an appointment with an unrelated leader for me.

First of all, you said you were not familiar with it. Since you are not familiar with why he wants to read your information, you can pretend not to see it when you see it, but the phone number is different.

Then the phone is obviously more sincere than the text message, but you should think carefully about how to speak before making this call. After all, you want other people's things.
