Sales people keep calling from Granite Telecommunications pretending they are the "preferred" VOIP provider from our corporate office. They are NOT. I refuse to answer shady sales calls from lying sales people. Saying you are the "preferred" provider when you are NOT will make me run from your business, not sign on the dotted line. In the phone service world, they may be trying to "slam" us for all I know. Not answering any more calls from GRANITE!
