Andrew points out that Kyoto and Osaka are near each other and that was probably behind the offers from Expedia that I had complained about. Helpful info that I didn’t have, but unfortunately, it got worse.

A few days later I received email from Expedia

To: Steve Portigal
Subject: Steve, here is your itinerary confirmation for your 01/02/08 Osaka trip
[deletia that makes reference to our Osaka trip multiple times]

Even more concerned than before, I wrote them and received this message

The next message is even worse.

Dear Expedia Customer,

Thank you for contacting us.

Kyoto, Kyoto-fu (Change name) Expedia.com itinerary number: 121380781812

If you have further questions, feel free to reply to this e-mail…

No actual communication. Is anyone out there? I try again.

Dear Expedia Customer,

Thank you for your immediate response.

Please accept our apologies for the misunderstanding with your hotel reservation. We regret any inconvenience this may have caused you.

Your itinerary serves as a confirmation of your purchase, and we’ve sent an updated copy of it in a separate e-mail. You can also access your itinerary online at any time. Here’s how:

Again, no one is addressing my key question: why does my Kyoto reservation keep getting referred to as my trip to Osaka? Once more into the breach…

Dear Steve,

Thank you for your reply.

Please accept our apologies in regards to the misunderstanding with your reservation. We regret any inconvenience that may have occurred and would like to assure you that every reservation is important to us.

Your problem may stem from incompatibility between your browser and our system. We have already escalated this technical issue to the appropriate department.

In the interim, your hotel reservation at the Hotel Monterey Kyoto is confirmed while the “OSAKA” tag line have caused you such inconvenience, the printed itinerary of your reservation is still binding and a confirmed reservation for a hotel in Kyoto, Japan and not in Osaka.

So somehow my browser is causing them to send me email messages about a different city? The crucial piece of info (thanks, Andrew), that these are nearby cities, never appeared, and a spurious technical issue was blamed (it’s not a browser issue; perhaps they want to blame the model of car I’m driving for the emails they are sending?) but at least a human being intervened and confirmed that what I thought I bought was indeed what I bought.

Great job, Expedia people! Ridiculously poor support to go with a rather silly system! Let’s hope we don’t have an actual problem at any point.
