Tell them not to call you anymore.
I had Medco call me at 9am or something when I had something like a 4pm feeder start. Told me he was gonna save me some money on my prescriptions. I said I was sleeping and he woke me up. He asked me a good time to call?
I said after 2pm, I swear the phone rang at 2:05. He goes over my prescriptions and says he can't really save me any money. My only long term 'scrip doesn't have a generic equivalent. I told him NEVER call again. They haven't, I've since gotten rid of the landline. Too many political robocalls, (funny they can get around the do not call list).
