I paid Aunt Betty $150 for seat selection on a flight to the UK—but months later, I found out they never passed the payment to Singapore Airlines.
I had to pay again just to secure my seat. Despite trying to resolve this for 3 months, I’ve received no response or refund. Very disappointing service. They encourage you to write in, but they never respond. Called and they mentioned that they will pass on the complaint to the relevant department. They never reply to your queries. After writing and calling more than 10 times, still get no reply to my claim for refund. This is probably their tactics - to wear you out and hoping you will not just leave it alone.
Better to pay Singapore airlines directly even though it is a bit more expensive.
If you purchased your flight through Aunt Betty then wait until your flights are completed, in case they cancel your flight/s, then instigate a chargeback for the $150.
