Well as the Tech guy and 'official' DNC list (FTC and State DNC list) dude for my company, i can tell you that the odds of your case even making it to court are going to be pretty low.
let me tell you the easiest way to make money here.
Get on the FTC list, it is FREE!
www.donotcall.gov - registration only takes a few moments + a valid email address.
if you live in a state that also has a State handled DNC list, get on that too. that one will more than likely cost you any where from $2 to $15 bucks.
print out and keep the verification emails from these two sources as the DATE you sign up will be important for your bargaining power.
NOTE: each state is different, but the FTC list has a 30 day grace period from the date you signed up until you can 'ding' the telemarketer for calling you.
also print the list of the TYPES of telemarketers that can still call you regardless of you being on the list. typically its charitable organizations, politicians, and banks.
those people you will have to specifically tell them to not call you again. SPECIFICALLY state: 'Please put me on your Do Not Call list.'
Do it nice, do it quietly. 9.9 times out of 10 if some one gets angry the phone number is added to the internal dnc list the moment the call ends.
if you do it nicely, it will just get added by an automated job based on a call result code, or depending on how low tech the company is, just written down and possibly lost.
now that you are on the FTC (Federal Trade Commission btw) and your States DNC list (if applicable) and you are now on the companies internal DNC list, you are set to try and make money with out going to court.
once you get a call after getting on all of these lists, and you are past the grace period for signing up for said DNC lists, you need to write a letter of complaint to the offending company.
more than likely nothing will occur if you have only been called one time. my suggestion is waiting until you have gotten more than one phone call.
in your letter you need to inform them that you are going to file an official complaint to the state and federal agencies.
alot of times, the company will offer you an out of court settlement to not do that.
NO ONE wants the FTC or anyone else to know they even screwed up to begin with let alone pay their own court fees to defend them selves in court.
its cheaper for them to just pay you off to be quiet.
all of that being said MOST companies do their best to abide by all possible DNC lists. its in their best interset to do so really. whats the point in calling some one who took the time to get on a list to not be called? odds of making a sale to that person are pretty low. so why spend the time and effort calling them.
also the AG(attorney general) for their state can shut them down with almost no notice if they get too many complaints on the same company.
one last exception that i forgot to mention - the EBR (existing business relationship) clause!
if you have done business with a company within the last 18 months, they have the right to call you even if you are on the state or FTC list. you have to specifically tell them to not call you again to stop the calls that result from an existing business relationship.
the individual telemarketing companies internal dnc list must be applied to all calls regardless of EBR rules and it takes priority over the FTC and state lists.
also the companies internal dnc list can purge you from their list after being on it for 5 years, FTC drops you after 10 (if i remembercorrectly) and each state has a different length on how long they decide to keep you.
i have had way too much caffine today...(my excuse for any crazy ass typing or spelling)
