Complaint Review: Justfly

My complaint is with Justfly on the internet.  On March 7, 2020 I booked a flight on Justfly.  It was for 2 nonstop flights (Philadelphia/Nashville) for a cost of $254.00 flying with American Airlines.   After completing all information/credit card, the final page came up to finalize it.  It had two lines with the flight info.  At the bottom right the cost showed $254.00. This is exactly what I wanted.  I clicked book.  The last page came up and said I would be getting an email in a couple of hours confirming everything. 

When I looked at my email hours later, it was changed.  The nonstop flight #1640 with American Airlines going to Nashville was correct.  The nonstop flight #5197 coming from Nashville to Philadelphia with American Airlines was changed to a one stop flight #4495 and #148. The cost was reduced to $209.00.  This is not what I wanted.   I was willing to pay the additional cost for two nonstops.     Later in the early evening on March 7 I went on Justfly web site to see the original coming home nonstop flight I had booked and the cost jumped to over $1300.00.  The website says you can cancel within 24 hours.  When I tried to cancel early Saturday evening, March 7, they were charging me $75.00.  (I went on the Justfly’s site Sunday morning and it is almost $1600.00!)

I went on Justfly’s site once again to try to contact them directly. I clicked on Customer Support. I could find no way to contact them directly regarding the change they made.  I  tried Justfly on line chat https://ww.justfly.com/service/support  (there was no live chat) I tried Phone number 800-717-5015 (no option to choose complain.  So I chose my booking and waited 25 minutes and hung up)

I have to keep the flight, so I don’t want my money back. The flight is for my son who doesn’t like traveling by plane, so the least amount of time getting off/on a plane is best for him.

How is it legal for Justfly to change part of the flight after clicking book?  I should be able to get what I originally booked and paid for.
