I tried to make a purchase online with volaris but it said that my card didn't go through. I went to volaris ticket booth at the airport in Tijuana and decided to pay in cash after they checked that I didn't have any reservation. The lady took my payment in cash. She didn't give me a receipt just the actual tickets. Two days after I found out that my card did go through. I called them regarding this matter but they keep on referring to email. In asked for a receipt from volaris that I paid in cash, they said that I never paid in cash and that I used a Mastercard. I don't even own a Mastercard. They have a payment with mastercard for the tickets I purchased in cash at the airport. Their doing something illegal. I have been trying to contact them but they give me the round o round. I have tried to explain to them that they took money from my capital one card as well as my cash but nobody is listening.
