call on caller id while I was out don't know who it is

its lady from Purple Heart its a OK number

Not necessarily.

Tell us more about this "lady from Purple Heart".
Website ... physical address ... reason for call.

they say they are a charity for veterans and are asking for a donation. I  could not find out any info about this organization so to me its just a scam. If you want to help veterans help those where you live and the veteran organizations in you area.

If your a past donator they call to tell you that they are going to be in the area with their truck on a certain day. Then you can collect
old cloths and leave them on your porch or door way for a donation. Not a scam
