Thank you for the information above - I will try to end these annoying calls by contacting them.

I was harassed for months by this number.  You could not fax back and you could not call the number. Phone company would not change my number without charging me. I was unable to actually block the number.  So I had to get a fax machine and hook it up to my home phone. I finally got them! I was being harassed by a DVM service. They have a contact number of +1 888-675-9765. I called it immediately and had my number removed.  There is also a number to call if you have the Reference ID that is actually on the fax that you can call and it is automated. You have to be able to receive the fax in order to get that.  I am hoping that I have resolved this once and for all.  It is very annoying when it happens at all times of the day and NIGHT!  And not just once - they have it set for auto-redial! Good luck everyone!
