Pissed off with early unwanted calls

Early morning of every day, I will always receive toll free calls and this will always starts my day as Mrs. Grouchy. I do understand the call center job because I was a call center agent before but then receiving calls first and early in the morning is not good most especially if a person is still sleeping. ARGHHH! What will I do with the phone is that I will unplugged it so that no calls will come in while I am still trying to have few minutes to few hours of my sleep. Sigh!
