Calls same time everyday. Person never leaves message. If they're not courteous enough to leave one, I will not answer or reply to them, as they're obviously trying to cold call potential business.

keeps calling, doesn't leave a message on the answering machine

Rings phone number twice a day every day,morning and night. If you ring back cannot possible understand such a bad accent on other end so don't know who it is. Feed up been going on for weeks
