Be careful with this one, they try and trick you into accepting a $600 invoice. Don't update your information with them, once you do, they send the invoice.
i got a call today - asked if they could speak to a manager, i asked who was calling (thinking it might be a client complaint), she said "Alicia from 411 webconnect" (sounded fishy) so i asked what it was regarding... "we'd like to make sure your company profile is up to date" i put her on hold and left for a bit. by the time i went back to tell her weren't interested she was gone. next time they phone (which i assume there will be a next time) i will simply say "no thanks, we're not interested in a $600 bill" :)
