Definition of Customer Service- provision of service before, during and AFTER a purchase

Imagine this... about to board Jetstar flight , 5 mins before announcement flight wont happen as no plane to provide service as they lost one from Bali.. queued up at desk got a $8 refreshment voucher, delay 5 hours... sound familiar
happened to us yesterday out of Adelaide .. finally got back to Melbourne at 1830.. problem pre arranged parking at airport had expired.. extra cost $30.. rang parking people regarding this told me to contact Airline.. did that .. response from Jetstar sorry we cant help...
Its not the money its the principle.. go back to the definition ...wont be flying these jokers again...happens too many times to too many people... Senior mgt need to start listening to their customers or pretty soon that will be singular...
