Had a hotel in India charge my USD even though I chose INR on the slip and asked the front desk to process in INR when I handed the card over.

Is there an easy way to dispute this with Citi without having to do it over the phone or chat?

I'm doing it via chat on my account and the guy tells me my card has a 3% charge on my card, and then he tells me that I don't have... took me 15 minutes to finally get him to open a dispute for me. Wow, how amazing CSR is.
