Just had the exact same thing. I didn't let him get quite as far before I told him I wasn't interested. He thanked me and said to have a good day. I'm guessing a polite scammer trying not to raise red flags.

Received a call from this number,  I do not know how they obtained my private cell phone number.   The dude said that from various databases.   That is why I hate giving out cell phone  number.   This is upsetting.   They need to stop giving out these numbes.   This should be illegal practice.

"That is why I hate giving out cell phone  number"  But it seems you gave it out in the first place.  Also, no one needs your number to call you, all they need to do is dial the right set of digits.  What they need your number for is to know who they are calling.

Said he was collecting money for our underfunded local police department, but wasn't even calling from a local number. Probably a scammer.
