I get a call from this number every day which I am sick of. I have even blocked the number and they still call daily.

I just got a call which I will add to my block list. I will now get no ring but will get a list of blocked calls on my phone.
I have the Panasonic cordless telephone Model kx-tg6842b (2 handsets)
You can block 250 numbers plus kill the one ring that existed on earlier models that only allowed 30 blocked numbers.
The one handset model sells for $70 at Amazon.

I get SEVERAL calls a day from 202 area code. Usually they hang up when I answer but some do talk & ask for my DECEASED grand parents. Yes, we live in their house but how many times to I have to tell you they are no longer breathing air for you to take a hint!! QUIT CALLING MY NUMBER!
