Actually - it depends on who it is. The law does NOT protect your line if you've provided your number to a company you have business with, and their affiliates. Most people don't read that fine print when they fill out forms or give away their info., or understand how the law really works. For instance - let's say you rent a car, or sign up for a store card somewhere. Unless you have explicitly stated on that form that you do NOT want them to contact you, they can. That store/business then has every right to contact you, even if you're on the DNC list - for promotional purposes, to tell you about new products, for surveys they do for input on their services, etc. Some companies by courtesy do place limitations on what you agree to allow them to do by stating it explicitly (ie: "contact for the purpose of ______"), but not all of them do. The best you can do in those cases - where the call is legitimate and coming from a company you've given your info. to willingly - and/or their parent-companies, subsidiaries, etc. - is to tell them to take your number from their listing. If you've done that and they still call, THEN there are legal issues with solicitation and harassment. The DNC list does NOT make you impervious to all calls across the board - that's a very common misconception.
OMG, people. This site won't be helpful if you guys just SPECULATE who the number belongs too! It's a survey company and they are called to ask about the customer service you received from someone you've done business with. They are not restricted by the DO NOT CALL list.
I get DAILY calls from this and other numbers, claiming to be "US Auto Care". I am the do not call list, plus I have been telling them for over two months to QUIT calling me. I wouldn't answer it, but I listen to music on my cell via ear buds, so my phone answers on the third ring. I am not a foul mouth, but it is now a game in my office to whether or not I lay the wood to them. My bosses are very impressed with the calm way I tell the yahoos to take me off their lists. It doesn't do any good, they call back. The callers are not "native" American English speakers, probably they are from India. I add each new number to my cell's reject list and they use a another number. Other numbers they use include 856-295-5565, 321-403-4129, 512-379-2069,971-208-9936, 212-777-3456, 687-213-9459, 305-775-5429, 636-373-9464, 618-259-1869 and 347-329-4437
