I received a call from this tel # 303-781-0836 asking me for donations to support some kids this xmas, he said is a Denver Police Department program. I asked him for a website where I can make my donation, they only take donations by phone because they don't have a website, how weird.....

Mark just called me and introduced himself as a police office from Denver department and asked for donations to support kids program ran by the police department. When I asked him about website where I can look his program up, he hang up. I am trying to report this number to the police department for investigation. Such entrepreneurs should deal with the police!

Had a call saying they were from Littleton Firefighters Foundation. Can anyone verify?

They are not from the LFF. Just ask them and they will say no and hang up. It is bogus and do not donate to them. Just tell them that you will get back to them and never call back. If you are to donate to anything over the phone please ask for validation or just donate threw their website!

This guy goes by the name of Mark Stephens.   He calls up like he knows you by asking for the managers first name.  How he gets it, I don't know.  However, once you ask him again who exactly this person is with he stalls by asking you exactly who you are and telling you the address.  He gets defensive and acts as if he is going to somehow get back at you.  This person sounds fraudulent...
