Confused about confirmed booking on SQ
Hello, I'm hoping those of you who are knowledgeable about how SQ functions can help me understand a booking issue. We have booked ten PE tickets on SQ from LAX-SIN-DPS. They are booked on four different PNR's due to different travel dates. Earlier this year, I went to look up a detail on one of the bookings and found that it had changed to "unconfirmed". Per the agent I spoke with, the seats were reserved but not actually ticketed, even though we had paid for seat selections and had the e-tickets and receipts from the booking. After much discussion, I had to repurchase them at the current price. Needless to say, I was perturbed and had the agent (a supervisor, by this time) reconfirm all the other bookings. They were fine at that time.
Today I am downloading all the receipts and etickets that were needed for the evisa application to DPS. I found that another, separate PNR had become "unconfirmed". Same scenario - I call in to the reservations department, they tell me that the seats were reserved but not confirmed because the seat price that I paid for had become unavailable and now I have to pay the new price to confirm the flight. Again, I have the eticket numbers and receipts from the original purchase made through the SQ website.
In all my years of travel I've never dealt with something like this. There have been some minor time changes on the flights, and each time I visit the reservation and accept the time change. Does this automatically mean I accept that I have to buy a new ticket at that time? I'm at a loss to explain what has happened with these bookings.
