PEOPLE, do not do business with anyone who calls from a fake caller ID number. In fact, if you haven't called a company, don't do business with anyone that calls you to do business over the phone.
1st, they use a fake number
2nd They violate the do not call list
3rd they use some sort of deception to "re-introduce" themselves (spoke to you and you were busy but said call back ~ left a coupon on your doorstep when we were in the neighborhood ~ you asked us to call you the next time we had a special.... lies)
These are professional liars, designed to separate fools from their money.
If we can't trust them to not violate our preference to not receive these marketing calls, then how can we trust them with our money, our home, our safety, that they are the best option, that they are the best price, that they will do what they say???? WE CAN'T.
Besides the people calling are usually telemarketing mills. If you ask for a website, a license, a phone number, or anything that might tie them to a legitimate business, they can't answer because they have not SOLD YOU to anyone yet.
First, they deceive you, then they sell you to the guy who has to live up to their lies. The guy who can't get business without employing these liars.
You've been warned!!!
