Who called from 6789330200

This is a business line and our bill shows we have about 30 calls from the same number. All 1- 3 seconds long during business hours.  I have searched for this number and haven't found anything out on it. We have no record of the call being answered by anyone but we have charges.

This number will call every 10 mnutes and its a fax line! Driving me nuts....

This number is calling every 10 minutes for the past 4 hours. A very busy medical office and very annoying

This # has called me over and over. I keep declining the call since figured out it is a fax. Now it is filling my voice mail up. Att wants $4.99 a month to block it. Please make it stop.

i got a samsung evergreen with att and i can block phone numbers for free iam sure my phone not the only one that can do that.
