Who called from 2532369757

I keep getting calls from 253-236-xxxx numbers and none have ever left a message.
I block them after about the 2nd call from a number but then another call comes in with the same prefix and different suffix.
...
It is voting season, but this call came in at 7:57pm on the last day to vote (must be turned in by 8pm), so if they are some group trying to influence a vote it wasted effort, otherwise I assume they're just more scammers.

I just got a call from this no. When i tried to call back it wont let me connect either.

Called twice in the last three days and left not message.......my guess is clean your ducts.....I could be wrong.

Has called everyday for the last 4 days but never leaves a message.

The caller alleges to be "John" from the association for Paramedics and Firefighters and he is soliciting money. He is paid by a "charity" which spends its money to pay him. the website for APF is at http://www.afpcares.org/ and Charity Navigators at http://www.charitynavigator.org/index.cfm?bay ... 22#.Vlod2-JFwQI labels this as a 0.0 rated charity on a scale of 4.0.
