just got a call;calling repeatedly this morning, leaving no message

Called twice today didn't leave a message.

Maybe the call is spoofed for other purposes, but this is the real owner of the Phone number which is :     Zina Gotlieb DDS
Queens Cosmetic Dentist   718-578-4144  

This number IS being spoofed and it's most likely a debt collector, called the number back and a generic response comes on the line, "our system is inundated with calls please call back"  Now, my research indicates that the number belongs to verizon business offices in NYC BUT if this verizon then why don't they answer the call with a business greeting?
If it's a serious matter then whom ever is calling should PUT IT IN WRITING and STOP WASTING MY TIME!

Getting constant calls and no message.  I screen calls people so you're wasting your time!!!!!!!
