I paid for 5 days value parking at Melbourne Airport, $12 per day for a visit to Adelaide, on my credit card, when booking the parking place.
I was delayed in returning to Melbourne and tried in advance with a request to pay the additional amount needed but received no response nor information on the website how to proceed. On returning I could find nobody to contact or any information about how to proceed. In the end I exited the parking lot, paid the full amount of $72 for 6 days parking.
Since I had paid twice for the initial 5 days parking, I submitted a request for a refund of that amount. I received a form response to that request on 31/3/2022 but no action.
It seems like the airport is just ignoring any request and waiting for me to give up knowing that I am not going to go into some costly or time-consuming process. I have registered a dispute with my credit card provider.
The amount concerned is not large in my case but presumably others have had a similar experience.
