First of all, website very slow. Second theyve sent me a voucher in Brazilian Real but I first purchased in dollars. So this meant I had to use the Brazilian website of course after calling the customer service. While on the phone with the operator trying to book my flight the call ends. No one called me back. Next day try to call the airline again because my payment of the rest of the amount of my ticket ( used my voucher ) didnt go through. So while we insert my info on the phone the call ends again. I had to call 20 times before getting someone and finish the call!! Its the worst service Ive ever had.
