I'd confirmed seats for flights from Singapore to Colombo, and from Colombo to Bangalore. However upon reaching my airline gate at Singapore, it was discovered I'd been given different seats. After trudging back to the Sri Lankan Air check-in, I was told there was a change to a smaller aircraft (this was incorrect, the scheduled A320 flew eventually). After I protested the middle seats I was newly assigned, I was given a different pair of seats.
However, upon reaching the boarding gate, my seats were again changed, and new boarding passes issued.
Three seat changes within two hours! I tried to file a complaint, and was told to stand in a line that had 25 people in front of me. Upon sending an email to the airline, no response was received.
