Would not honor the rate that was guaranteed when I made the reservation on 9/23/17. The duty manager stated that it was because of the Government raising the travel per diem.

Despite having and showing the reservation and it clearly not warning an increase of the rate she continued to not honor it!

Only after a lengthy and conversation that a few people heard did she finally agree to what was promised in writing (reservation).

When did it become okay to NOT HONOR WHAT IS
/WAS CLEARLY STATED?

Check and confirm your reservation before they bend you over!
