I booked a flight which quoted me prices lower than other websites. but then price charged to my credit card was different from the price when I booked. even my email CONFIRMATION quoted the accurate amount, but again the charge on my credit card was more. Called customer service, they did verify this information but said only their billing department can handle such request; Billing dept only takes emails. I emailed them and was quoted to have a response in 6 hours (it clearly says that in their automated message). 2 days gone by and nothing. Called customer service back. They said they can see that I did email the billing dept but again only billing can resolve issue. They quoted me to wait until 48 hrs. 5 days have gone by, still nothing. Called back customer service, still cant help even though they do see the discrepancy but again referred me to the "billing" dept who does not answer (wondering if it this is just a scheme.) Tried to ask for a supervisor but was quoted that none is available at this moment and I cant even hold for one(how is that possible?). Said they would send in a request for a supervisor to call me back within a few hours. 2 days later, still no call back from supervisor.
Summary TLDR- how can a business you send a confirmation for one amount but then charge you another amount to your credit card.
