This is a telemarketing SCAM for several phishing reasons: Reduced Interest Rate Credit Cards, SAT (Dish Network) TV and Extended Auto Warranty. They call from both coasts on numbers that are bogus. Some even show as local numbers from just plain folks who have no idea their numbers are being used by telemarketers. Be advised that even if you are on the National Do Not Call Registry, your number could be removed, without you knowing it, if you change features on your phone, if it gets temporarily disconnected, etc. You need to verify that your number is still on the list every now and then, especially since it takes 31 days to "appear" or "activate" Dish Network has an escalation specialist in Colorado Springs who says, if you receive ANY calls after the 31 day period, call them and they can set you up in their "Sting Program" which provides you with faux information to present to the company as if you are going to order the service, and then they can trace who they are and press charges.
I feel your pain comrades. This is a situation that has caused great frustration to me since they also call on my business lines and I am a florist who receives long distance calls for flower orders and must answer those calls. The list of "Bogus" numbers is so large, I simply can't try to look it up before answering while the phone rings and rings. It looks bad for business.
