It seems that this is exactly what happened to our office in the last couple of months.
I originally posted this under the complaint section for NetOpus.net, but Qwest needs to be mentioned again here. Qwest was heavily fined by California PUC for doing what you are describing —back in 2003.
Just this year, going back the last couple of months, we fell victim to this same technique with Qwest and a company calling themselves NetOpus.net. NO verification, no authorization, no services rendered, yet we are getting charged $34.95/month through our Qwest bill.
So why is Qwest not doing something more to verify that the charges are legitimate??
It seems that anyone who wants to run a scam can simply give Qwest a phone number and company name and tell them to start charging the customer whatever they say to charge.
In our case Qwest was very quick to offer credit back, but would not describe how the NetOpus charges were authorized on our account in the first place. I would think that if Qwest was fined $20 million for cramming in 2003, is there not complicity in what they are doing today?
Until enough people complain and register these issues with their regional Public Utilities Commission, or with the FTC for interstate wire transfer fraud nothing will stop these utilities from playing this game.
