Unfair treatment and no truly collaboration

I know Qatar airways are good, but they very clever. If you book, something wrong, it happened it’s my fault, but it’s there’s, they quick to say re-book, pay , I want more money. As I asked the Airline to assist, they not interested and said talk to travel agent, talk to travel agent to assist, they say talk to Qatar. Spoke to Qatar and say triple to pay for another ticket or talk to the travel agent. They just want to make money. And thus of an e-visa, which I never needed before. I have app**** and paid the fee, still couldn’t fly after conversation to a rude supervisor (guy, forgot to ask his name “all he say it’s not his responsibility in helping me to achieve this e-visa requirement from Qatar) Now who is to blame How can you retrieve your money paid for your tickets. Everyone just passing the buck I feel it’s just a money **** Proof me wrong Especially in person Tom Dreyer
