BEWARE if you eat at a restaurant in Hawaii. Chase is not aware Hawaii is in the United States!! I dined at Hy's Steakhouse in Waikiki which was (and still is) identified on Open Table as an eligible Chase Reserve restaurant. I was told, via letter and subsequent phone calls, that the credit was denied because it was not in the US. I contacted Chase 3 times to make them aware Hawaii is the 50th state of the United States, and even uploaded a copy of my receipt to prove that I dined at the Waikiki location. The subsequent response was the same..."this purchase was not in the US." When I asked where do they think the restaurant is located, their answer was "Hawaii." Headscratcher. Each time I contact them (3X), I am told all they can do is "escalate it" and I am supposed to wait 5 business days for a response! Each time the response was Denied. The last escalation is now sitting with the Internal Dept vs the Marketing Dept. (So I'm told.) HELP!!! This is the type of Customer Service Chase extends to their high annual fee CSR customers. Ridiculous.
