I have found multiple calls that came during the day and leave no message. But last night at 11:15 they called and hung up. And again at 4:59 AM, they called again. I hate these schmucks!
Have received several calls from this number. No message left, do not recognize number and will not answer. By the way, I really hate these kinds of calls at 4:40 AM. When the phone rings at that time I expect urgent calls and NOT some annoyance call.
