Calls all the time and never leaves a message. Traced the number and it turns out to be some kind of bug extermination place. It's weird that the number shows as "wireless caller" on the caller ID. It actually seems like they might be a scammer, if they can't even call from a number that is in the business name. Either way, I will not be doing business with a company that won't leave a message and can't even bother to have the number calling in their name.
