Who called from 7015527488

This number is constantly calling and hanging up when it we answer.  It's quite an annoyance as they are calling a businesss

Same here.  Constant hang-ups, also a business.

Receive about 5 calls day to our business from this number - constant hang ups when answered - ID shows as SUPPORT INT

They call several times a day and then hang up. We also have a business and I really would like to kill these people.

Hold on.... you mean you have a business that literally KILLS People?  Kills 'em until they are dead?
Do you think you should be saying that here?
