Got a call from 8x8, which is a VoIP telephone service asking if they could send a proposal for a new phone system. All I had to do was give them my email address!
Said they were representing Verizon and wanted to send me a white paper on VoIP. I keep hanging up on them but they keep calling back. NEVER agree to let them send you the "white paper" - your information will be given to TONS of VoIP providers who will contact you saying that you had requested a quote from them. Fell for this once before and took 6 months to get everyone to stop calling and emailing me.
