I guess only those who have not had any issues that required customer support or just a company that did not want to scam you... Awful experience. I used GoToGate to buy tickets and during the reservation process I introduced wrongly the surname of one passenger. As soon as I received the purchase confirmation email; literally a minute after buying the tickets, I realized of the error and called the airline. They explained that the change could be made with no penalty fee if requested 24 hours after the purchase but that it had to be GoToGate submitting the request, not me. Here started a nightmare of a journey that so far has involved more than 20 conversations with 20 different operator to whom I've had to explain the situation individually every different time. Not once, after not resolving my issue, they have agreed to pass my call to a manager. In a nutshell, as confirmed by the airline and in a few occasions by GoToGate operators, GoToGate submitted the request to amend the name of the passenger after the 24 hrs window frame passed, even though I made this request GoToGate literally 15 minutes after purchasing the tickets. Result: the airline refused to make the amendment and they said that a new ticket has the be bought as they are now considering it a name of passenger. Every call to GoToGate is slightly different to the previous one. In one they tell you they understand the problem and assure you that a manager will get back to you with a compensation proposal; in the next call they say that they did everything by the book; just as they were meant to, and insist that you call the airline directly and resolve things with them....What else can be said? Oh yes, depsite multiple attempts to raise a complaint internally they repeatedly did not allow me to do so. I sent them emails and I would get a supposedly automated response saying that the inbox was not being monitored and instructing you to go to their website if you wanted to fill a complaint form. Of course you will then go to the website and the form is nowhere to be found; and then you will speak to an operator who will tell you that the complaint forms were actually disabled from their website and that they did not take complaints over the phone neither. And anyway, if that wasn't enough my enquiry was still not at a stage in which I could officially file a complaint.
