First, after the phone is connected, the other party hears your voice is different from the voice of the person he wants to contact, and knows that the number is wrong, so he won't bite.
Second, it may be that some telemarketers dialed your number and left on a business trip, so no matter what you say, the other party will not bite.
Third, it may be that your friends or acquaintances are joking with you.
So if you receive a strange phone call in the future, I suggest you hang up without biting.
These are my suggestions for reference only. I hope my answer can help you and make you satisfied.
