Keeps calling but doesn't leave a message so I have no idea who or what they could be calling for or about. If it's a 'collector' they really need to learn to leave a message rather then use an automated system that doesn't leave a message but keeps repeatedly calling phone.
I've been getting maybe 10 calls from this number per day, and, like the others, there's noone there, and if I ignore the call, they never leave a message. Quite annoying. If it's so important that they have to call several times daily, one would think that they'd eventually leave a message, regardless of how much the recipient does or doesn't want to hear it.
