This number has been calling me four or five times a day at all times (several times at 10 p.m.) for over a month. I never answered til today when I had enough! They asked for me and when I said I was unavailable (LOL) and asked if I could take a message, they said no and hung up. I've been registered on the do not call list and now I will be reporting them to whoever I can!!
Stop the irritation: Put the number in your contacts under "Nuisance" (or whatever you want to name them!) and set their number to "no ring", "silent", whatever your carrier/phone calls it. If there is a number blocking cell phone, I don't have it - but silencing their ring sure helps until something better comes along!
