Caller ID says Thriftopolis. I have my Phonetray software programmed to block all call with Thrift* in the name and so far it has blocked calls from Thriftopolis using the following additional numbers:
303-275-0130
303-275-0102
303-275-0096
This a rude nonprofit that calls several times a week this last month. I have asked them to pick-up my donations about a year ago. When they didn't show, I called them and they were bothered and ungrateful.
