I am disappointed! I'm appalled!

I am so disappointed in this airline. They provided me with incorrect information on my boarding pass (terminal B instead of Terminal A). And then blames me (the consumer) by saying i wasn't there early enough. Its only when i got to the security that he advised its the wrong terminal, but also couldnt explain why it says Terminal B, instead of terminal A. Airlink has the most unhelpful staff: Clementine (agent), Suprise (supervisor) and Sima (duty manager) who absolutely refused to help despite being provided with the incorrect information they provided me. Now they're claiming that the boarding pass says Terminal B because they dont have check in desks at Terminal A --- This is an international flight, and I checked in online. WHY THE HELL WOULD MY BOARDING PASS SAY TERMINAL B when supposed to be at TERMINAL A! Why would you do that and then blame me for not asking any of your staff? there was no uncer*****y. I had no bags to check in. I knew exactly where I was meant to go and what the assigned gate was. But because your boarding pass says Terminal B, i wasted time standing there, only to be told its not the correct terminal. Further action is being taken. Your terms and conditions do not negate the responsibility of providing accurate information. If I didnt board because of my own negligence, then I understand. But because of your information negligence?! that is disgusting!
