Never again taking advice from a friend who recommended this darn awful bunny hopping bs! I had entered all my information, scheduled my flight, and hit enter. Seconds later, I was informed with an apology, "Sorry something went wrong, please try again" Which I did but the problem happened again. I checked with my bank, and found out I was charged. I tried to contact hopper's customer service but kept directing me to their website with a list of what answers to whatever questions or problems ones have.
