Has called several times in last few weeks; always a different person; always asks to speak with a person who has never worked here; says this (unknown) person has given them our number as the place where they supposedly work.

After I tell them I do not know that person, then they ask if this is a place of business; do not give info about themselves; do not want to leave message for the (unknown) person; says this is a "personal business matter."

I tell them that if it is a personal call, then they should call the (unknown) person's personal phone rather that their supposed place of business.  Very annoying getting these calls again and again.
