I get it too :(

They call every morning, wake me up, and are too chicken to leave a message. For any telemarketers that might read this, whatever you are selling, I won't buy, simply BECAUSE you just called and annoyed me. Also, any call that comes in reading UNKNOWN, ANONYMOUS, blank, or have some weird partial number on my call display, I will not pickup, OR, if I pickup I will not buy whatever you are selling BECAUSE you just called and annoyed me.
TMs, are you starting to get the picture?!

This pest keeps calling me, and failing to say anything before hanging up on me.
