I issued three tickets today all at the same time. The first confirmation is: EXB*Q*W*For €**.**. This was correct. Ticket in the name of Katherine Roshodesh. ** The second confirmation number was for EXB*Q**. The booking I made for this confirmation number was for July **, from Venice to Nice, however, I received an email shortly there after and I noticed that the date of the ticket was for July **. I changed the ticket immediately and was charged an additional amount. I also noticed that my husband’s name was Misspelled. When I went to correct that spelling of his last name I was told on line that I would have an additional charge. For this reservation I got charged €**.** for Lisa Naysan and €**.** for Mehdi Nayssan. Each ticket should have been for **.** €. Not only was the name misspelled but the charge for the ticket was higher than the original booking. **The third reservation was confirmation number EXB*Q*W. On this reservation I was charged ***.** €, for a ticket that was supposed to be €**.**. The name on this reservation is Christine Ravan. ** Can you kindly explain to me why I was overcharged for these two tickets on confirmation number EXB*Q** and confirmation number EXB*Q*W? **I made all the necessary changes to reflect the correct date and flight and did all this within a few hours after the original booking was made. **I would like to request a refund for the overcharges that were incurred on all respective credit cards.
