I charged a couple of breakfasts at a hotel on Soi 13 in Bangkok a few months ago using a Chase INK card.

The cashier presented me with a charge slip in US Dollars and didn't understand anything I said about doing the charge in Baht. Don't think he was faking. But I wrote choice of currency not offered, incorrectly billed in US Dollars on the charge slip (probably should have photographed the slip but did not have my cell).

When the charge for $12 odd dollars came through I called Chase (yes, I know about the legal need for written notice to billing error address) and disputed the entire charge. Chase mailed me some paperwork about what was the problem--the usual foolishness since I had fully explained the problem to the phone rep. Never sent back the paperwork--my bad.

But, amazingly enough, just got a notice from Chase that they have credited the entire charge to my account. Took 'em about three months, but, I assume they sent a request for info to the hotel which never responded. Or, maybe they just ate the charge.

Saved about 50 cents and struck a blow for consumer rights! ^
