Flighthub Flight hub cancelled a ticket bought 8 months in advance because I noticed a change in my itinerary . An extra 8 hours layover was added to my trip. Internet

 I booked my trip 8months in advance. I booked on May 2 leaving Nashville to Lagos on Dec 2 returning on Dec 19. Flighthub sent a mail on Oct 16 saying the airline has changed my itinerary. I called to find out that the return leg of my trip had been changed. The layover time between Chicago and Nashville was changed from 3 hours to 8hours. Instead of arriving at BNA at 05:27pm, the new time was 22:47pm. After 3 days of multiple calls and drama, I got an email yesterday from Flighthub informing me to call customer service line. Imagine my surprise, when I was told that the airline has refunded my ticket . The airline is Lufthansa. I called the airline who responded that firstly-they never changed my itinerary and secondly - they never refunded my ticket. Flighthub does not have a customer service culture . I talked to 4 customer service agents and 2 supervisors. The supervisors are the WORST !! I was informed to take the matter of my refund money up with airline- Lufthansa that I never paid to. So, I am stuck with no ticket and no money. The ticket price has doubled and my refund is hanging in the air for a trip booked 8 months in advance. Flighthub management needs to determine what their company stands for. Is that how a responsible company treats its customers?
