hangs up

yes it is a charity, it's most likely special olympics of your state, beware these calls will NOT stop until you either donate, in which case you will get the same problem in 6 months, or you ask to be taken off their calling list, in which case you will get the same problem in 5 years. If you do decide to be put on their do not call list i advise you to request to put on their "global lockout" DNC list, as this company calls for a ton of charities and believe me they will call you for each and every one, and the only way to get them to stop is being put on their dnc list seeing as how the national dnc list "does not apply to non profit organizations"

I just got a call from them at 7:30 p.m.  I called it back and it is a phone charity of some sort.

Calls coming in marked Medallion.  Who is Medallion?  No message
