Got a call on my iPhone 5s and did not answer. No voice mail was left. I do not answer my iPhone 5s to phone numbers I do not recognize After reading the other posts, on this website I am glad I did not answer.
Called me. Answered because a similar number kept calling me that I blocked and wanted to see if it was the same message. Claimed to be "Comcast", hung up as soon as I heard - It's a scam. They have a bunch of these fake numbers they use to call and scam people. If they really wanted to get in contact with you, they would leave you a message if you didn't answer (I've sent them to voicemail before and they didnt leave one), they would email you, or alert your account.
