Costco Citi Bank Visa Issued me a new card because of fraudulent activities. Received my new card, Verified that I received. I have had to call them over 8 times in a 24 hour period to allow purchases to go through. I told them I was planning a vacation, Because My card would not work and had to call to verify every transaction I lost reservations that I could have gotton if My card would have worked. I am very upset about how Citi bank is taking care of this, I have called many times told I was on a recorded line, only to have to call back multiple times for the same issue, I was given a reference number only to find out after they reset their computers on 6/6/2021 that my reference number didnt work, they couldnt find any notes, I have called multiple times and the situation is still not taken care of, they really need to save there notes, now Im told that they are sending me a letter that I need to fill out and that could take 4-5 days, no thanks I will stop using my card, I needed access to my card especially after citi told me that it was cleared and they could not see any issues, only to have constant denial of my card trying to book a vacation I cant play this game, Horrible Customer Service, Especially since I was a loyal Customer
