You had one job?!

So i requested for the tap and go function to be removed from my card. Had to publish a review here to get a response. received a call saying it was done. If it was , please explain how a merchant (without asking me permission- this is the reason why i want it off) tapped my card and it worked? why is it still active? FNB is this a very hard request for you guys to follow through on? What am i paying (insane) service fees for if i get no service?
