We have received a lot of calls from 212 2017278 in the call center where i work, they always wanna fly from or to Bogota, Colombia. They always call with different names and use differents credit cards to pay incredible fares. They don't care if we just have first class, they pay USD 30,000 without any problem. The thing is, we believe is 'the same people with acces to credit cards information'...Scary doesn't it?
