I have received several calls from this number, the first time I answered they hung up and then the next couple of times it went to voice mail but they didn't leave a message. I don't mind calls but after 8:30pm is next acceptable, my own family knows not to call after 8:00pm unless it is an emergency.
Same story here. Received 3 calls from this number, all in the evening after 7pm. I didn't pick up as I don't usually answer from numbers I don't recognize and they didn't leave a voicemail. The 4th time they called, I answered it and they hung up immediately.
