ReservationDesk.com review: Issue with your company

I am a 73 year old veteran traveling with my wife who is almost 70 to see my son who is stationed in Germany. We encountered a long delay leaving O'Hara to Frankfort which caused us to miss our connection from Frankfort to Stuggart which is where my son is based. When trying to reach Expedia which is the company we used to book our original flight, we somehow ended up calling Reservation Desk. it was a terrible situation, we were on the plane and the flight crew would not allow us to get off the plane due to the fact that they did not know when we were leaving. It was very crazy, especially for us.
My phone was dying and we were running out of time. I finally got a strong enough signal and thought I was calling Expedia who we originally booked with but ended up talking with an agent at Reservation Desk. He did NOT identify himself as a Reservation Desk agent but led me to believe he was with Expedia and could fix our problem. Due to the delay, we only wanted one of our flights cancelled (from FRA to STU) and re-booked at a later date. However, he took advantage of the situation knowing that we were desperate and cancelled our flight back to the states from FRA. which was crazy and completely un-necessary as we are not coming home for another 10 days and there is and never was an issue with that flight. He told me that he would take care of everything and that I did not need to worry about a thing. Well, he did take care of it alright. He completely rebooked our return flight, which we never wanted and now we are paying way more than we started out. I called the customer service number and talked with another agent who told me "the flights have already been booked and there is nothing I can do". I responded and said that was not acceptable and that something needs to be done. I noticed in these websites Reservation Desk often responds and wants the customer to contact the "escalation team with a website (support @reservationdesk.com). Well, I did that and have heard nothing. Our original flight back to the states was a quick one. Now the Reservation Desk agent has us flying from FRA to Houston and after an almost 4 hour layover, we fly to STL. I just asked to be put back our original flight... that does not sound like a hard thing to do. So far, you have our money and the people I've talked with have not been willing to cooperate and help us get back on the original flight. While l'm not a big traveler, we all know flights change daily and they can be modified when required. I'd certainly like to think given the circumstances, someone from Reservation Desk would come to our aid. We will see. It is clear to me that you only have one goal in mind... to make as much money as possible and when asked to fix something they did, they put up a smoke screen and say"nothing can be done". This is not the type of company anyone wants to do business with. I'm hoping their support team will contact me but the clock is ticking. We all know in this day and age, every dollar counts... it certainly does with me!
I'm hopefully waiting!
