I emailed VZW customer service & they stated I can only block text messages that are 10 digits in length. I replied to the 5 digit number with the message
STOP, QUIT, CANCEL, END and UNSUBSCRIBE
but I am still receiving unwanted text messages. This is costing me $$$ and I do not like it.
i got the same....the ones tht charge u 9.99 a month. i didnt even open it nd it still charged me. i already had them blocked on all my phones through verizon sumhow it went through. so i jus called up verizon again explained wut happened nd they took it off, all the charges. so mayb jus go down to ur local verizon store and tell them u want them blocked from coming to ur phone. hope i helped u out!! good luck
