Unblocking of card for RCS app use

It all started like a fairy tale. Nice attitude and such a helpful sounding voice when I called RCS on ********** as I had just now tonight for the first time tried to register on the RCS app on my cell phone, and the app kept saying I'm registering with the wrong cell phone number. However when I phoned RCS (above number) they asked me for my ID number of witch i had given it to them without even making a mistake, they said it was the right number when they asked for my addresses I have them both and it matched the system they asked my cell phone number and that matched too. All just to get my card unblocked. THEN DA DA DADA. THE **** HAPPENED. THEY WANTED TO ASK ME SECURITY QUESTIONS AS IF THAT INFO WAS NOT CORRECT. But the questions they ask are madness. How can you ask me what I paid RCS in October and not know what year the October the question is based on. Now how can I give the correct answer if every month of payment differs. Obviously I have not yet paid in October 2017 witch is now so how must I remember a year ago's payments values. Does this not seem unfair of a question. Now they say they can not unblock my card because they don't believe I'm the correct card holder. So not good. So not fair. How can I even think of giving a rating on service when it's so poor it does not deserve a rating. Well that's my story of RCS. Perrrrrrthetic.
