REFUND OF $150.00

Today 06/14/17 around 11:00 a.m. made a reservation with Cheapoair.com and while I was making the reservation some window will open up asking me to get the seat option for varies prices, I didn't want to pay for upgrade seat, all I want was the regular seat since the flight is only 1 1/2 flight. the system didn't allow me TO GET OUT so the only option was to move forward, so I realized that it booked and I realized that the price went front 499 to 534. So I called the at 11:05 asking them why the increase and I didn't want to pay additional for the seat, so I asked them to cancel the booking because to me that is misleading, so they send me a cancelation email and noticed that the company was charging me $150.00 for cancellation fee, even if there was the system error.  I spoke to some many people today and it seems like they don't understand and they want to put the burning on me.  IT IS NOT ACCEPTABLE THAT THEY WILL MAKE $150.00 DOLLARS within few minutes of the purchase and cancellation.  I called several times to dispute and no one seems to understand the reason of the cancellation.  because the misleading seat.  I called 1-800-525-0400 (that line takes you directly to india), I called 1800-566-2345 and (212) 478-0335.  I asked to speak to someone within the USA.  I was told that I want to dispute, I need to speak to someone in INDIA.  I want my refund and I am not going to give 150.00 for a cancellation within few minutes.  Please someone reach me (818)389-2181
