Amtrak  - I thought I was booking a room and I booked at roomette

When I booked a special 2 for 1 to San Juan Capistrano from Bend Oregon I thought I was booking a room with a lavatory and I got a roomette. Luckily after boarding and seeing what a roomette was we were able to upgrade to a room. But because our tickets had been scanned they said they could not give us the 2 for one deal. So we paid an additional $741.00. When we got to LA we got another upgrade for the way home, this time they said they could not give us the 2 for one because the date had expired for the deal so they charged us an additional $610.00. I talked to one of your employees and they said they thought we were treated unjustly for being in our 80's. Well my husband is 86 and I am having my 80th birthday April 23. That is why we went on this trip to visit our kids to celebrate my birthday a little early because of your special. We would not have gone had we known it was going to cost this much. Our original booking was very confused when we got our e-mail, she had booked us completely wrong. That is why there are two charges on the same day. Jacalyn Jo Haworth Reservation #EBA49DBEND
