Have had several calls from the same number at various times of the day and night. Caller ID on my phone says N Carolina Call. Just like everyone else, doesn't leave a message. I'm in Colorado.
They keep calling my elderly mom's place at all hours, including the 8am hour of the morning and evening. She doesn't sleep well at night, so often catches her sleep in the morning, and they are waking her up. Never a message. I tried reverse calling, but the number was not a call back number.
