I love my Citi Prestige card and always use it when traveling. My wife and I had a 2 week trip to Italy in XXXX, and we had huge security problems while staying at 1 specific hotel. I had originally booked 2 nights, but had to leave in the early morning after the first night. Security deposit box wasn't working, door wouldn't close ( physically close ) so we had to take turns sleeping and watching the door. It was an ordeal. This was reported several times to reception, but was never addressed and we had to leave asap next morning and find ( and pay at higher rates since it was at the last moment ) for another hotel. I submitted a dispute through Citi Bank for partial credit ( 1 night out of 2 ), since Hotel refused to refund us. Citi had our backs ( thank you Citi! ) and resolved the dispute in our favor. Again, for partial credit, not the whole amount since I'm not trying to scam anybody. However, I received a very confusing letter a few days ago asking for signature and to provide proof. I'm not sure what I'm supposed to sign or provide, if I had already provided my statement when I submitted my dispute and Citi already resolved the dispute in my favor permanently ( not temporarily ) and sent me a letter stating the matter was closed.
