When I contacted them, they didn't even really read the email through, the responded that they were sorry that someone is harrassing me and give me instructions how to block them. I responded with "please read my message again, I know how to block, but it is'nt letting me do it", they just had guesses why it happened and said if I have any more problems, let them know. I guess they will get it fixed one day. Glad to see I am not the only one having problems.
FINALLY FIXED!... Well at least I can block people if needed, hopefully every one else can. Now they just need to fix it where you can block the unwanted ads like big car dealers, mattress stores and auto repair service shops from being seen day after day.
