A very rigid and completely not compassionate extremely not professional attitude for special situation! I clicked on a fly by mistake because was near to my fly, I've payed and after I received the itinerary and I saw the mistake I called to explain the situation and request to change the payment to the right fly but they refused saying that the policy say if you buy you cannot receive the refund or change the fly. I explained that was a mistake because I didn't saw the difference between the both flights but still didn't accept any explanation. Then I had to pay another ticket for the right fly....I am extremely disappointed by Trip.com inflexibility and lack of understanding in special situations. I consider this a abuse and unprofessional attitude!
