twice before calling again.  This method may help you put an end in receiving mysterious telephone calls.

Contact your telephone company and report the annoying or harassing 
calls you’ve been receiving and find out what they can do about it. You 
probably are not the only one to complain about receiving mysterious telephone calls

service provider can help you track down the origin of the harassing 
calls or can block unwanted calls if the prank caller is using the same 
number. If you are willing to change your phone number, your service 
provider can assist you with that and can also give you options on how 
to protect your new number.  You

police. As much a possible we do not want to make our lives complicated 
by involving the police but if the calls are really frightening and 
harassing you need to report the incidence to the authorities. But of
