I used Merrill Lynch travel services to book my XXXX trip using my credit card and did not note any penalties for changes on their website or tickets. In addition, my eticket receipt did not arrive with any change fee disclosures. I needed to change my return location from XXXX, XXXX to XXXX, XXXX, which is also the city that I should be flying in to, but when I called the travel center they informed me of all these change fees that included a {$270.00} airline per ticket fee and their service fee of {$30.00} per ticket. Even though the total price is now lower than what I originally paid for ( {$810.00} compared to {$1000.00} ) they will not refund me the difference or apply the credit to the airline penalty fee. They blamed the airline for these fees and for not refunding me the difference, so I called XXXX and they told me that they were not able to help me because I did not purchase the tickets with them. I asked about the price difference and they said that the ML should take care of that for me. I called them back and they said no and that they could only waive their {$30.00} change fee. I was not appropriately disclosed of these terms and would like to see a change without any penalties or a full refund. It appears that ML is engaged in the travel business without clearly disclosing the fees to its customers.
