A person called unsolicited from this number, saying he is representing a free service matching people who want to further their education with educational opportunities. He said they found me from some site where I was seeking to get additional education - not true. He started asking me questions, and I told him I was not interested and hung up. He called me right back, accused me of being rude for hanging up while he was still talking, and continued to question me. I told him that I did not have time for this conversation and hung up again.
Same situation, regarding furthering my education opportunities. The first time I picked up I was at work and told the guy I was at work. He kept talking. I told him I don't have time for this and he kept talking. I hung up while he was midsentence. This was yesterday. Today I already have 3 missed phone calls. Problem solved: added the number to my contacts as "spam [***]" and marked the option "send all calls to voicemail". Tahdah!
