A few years back I signed up for the EY ADIB top tier credit card (forget what they called it but you get the idea) & the customer service experience in; getting miles credited, bonuses posting etc etc was absolutely & utterly hideous. Never ever again will I entertain dealing with that esteemed organistion! Some friends ignored my advice - seduced by bonus sign ups......they deeply regretted doing so! Be afraid, be very afraid!
hence I went for AMEX Platinum
