Bought vacation package by paying with Citi credit cards, had problems with merchant and disputed the transaction. After a month Citi cards wrote me official letter stating they can not help me with my dispute. Spoke with many supervisors but noone seemed to care about my problem and just told me to deal with merchant myself. Never had that kind of issue with XXXX XXXX or XXXX card. 
Very horrible way to loose a loyal costumer.
