We received our MCI invoice and there are 18 calls from the 248-536-6226 (Farmington MI) and 19 calls from 414-831-1002 (Milwaukee WI). I called MCI asking for the fraud department because these telephone number are disconnected. That took her 20 minutes to do this only to find out MCI is connected to Verizon which is OK, but this process took 45 minutes. In order to get the credit on my account I have to bring my Vendor in and have them write a letter stating where the "breach" on my PVX? system is & to make sure it is in a secured location. Good Grief! I don't have anyone working at 12:09AM to do an inside theft on my 800#.
TO: The owner of this number: Your telephone is calling my toll-free number. You are interfering with my business. You are restraining trade for my company.
My guess is that you must be using a automatic dialer.
These calls are coming from a carrier called Comity Communications. There are a foreign held limited liability company providing VOIP origination and termination services.
My guess is that hackers are using their service and calling into toll free numbers trying to make outbound internatiol calls free of charge on your outgoing lines!
If Comity is aiding them maybe someone should report them to the FCC.
Be careful! Be sure you lock down your telephone systems so that these guys cannot call in on your 800 number and go out on one of your other lines.
Based on the time of day on my bill...this is what they are trying to do!
