Called today, a Sunday! Jerks. I had already blocked this number based on 800 Notes postings. Interesting comments about one or two rings and people calling back cuz they think they missed the call. That explains a lot of these calls I get on my cell phone too.
Just went over a long list of incoming calls I didn't answer. The numbers 904-435-3419, 3420, and 3421 came up over a period of several days. Must have a block of numbers they're using.
