HTC One M8 Block Feauture

I just recently got the new M8. On the older version of the HTC One, you were able to block contacts by hard pressing the contact and blocking them from the contacts. You have the same option on this phone, but I am still receiving calls and texts from people that I block. Is anyone else having this problem?

That is definitely odd. Maybe try clearing the phone app cache. Or you can try blocking them by calling your carrier that way they can't ever reach you.
