If you've only been sent confirmation of refund 3 days ago you need to give it a little more time.

As much as I agree payments should be processed in a timely manner, I think you will find for the rest of your complaints, the reason you are getting the upgrade so cheap is because it's a last minute upgrade when they have been unable to sell the seat. Obviously this can only be done at the last minute,

If you want notice, pay the full price. You really can't have it all ways for goodness sake.

There terms are you are told you will be refunded within 5 days it has been 13 days, so I have given them more than 3 days. Also the terms are you will be informed 1 -3 days before your flight and no later than 4 hours before your flight, so I do not think it is okay to wait right up until boarding when you are not informed of that being the case. The upgrades are not cheap by the way I am waiting on a refund of $876 AUD.

"Also the terms are you will be informed 1 -3 days before your flight and no later than 4 hours before your flight"

In your first post you say you were informed 4 hours before your flight so I don't see really see what your complaint is here. Of course, the slow refund is a different matter.

My problem is I was informed 4 hours before my flight ( Upgrade pending subject to availability. Please check status with AirAsia X staff at Melbourne airport ) so you are not in fact notified with a final response until boarding and this is not stated in their terms and conditions.

Alright, fair enough then.

The upgrades are cheap in comparison to the full price seats.

Booking with Optiontown is a risk. It's like buying a lottery ticket. The costs of the ticket are by far outweighed by the potential reward. Setting aside the delay in receiving the refund which is a request and justifiable complaint, when I register for Optiontown for an upgrade which I have done with and without success, I pay for luggage and Hot Seats and include that in the cost of the upgrade. I work on the basis that if I do not get the upgrade I have both luggage and seats of choice already in place. Yes, you get extra luggage allowance bout I'm prepared to forego that cost in comparison with the still considerable saving if the upgrade is successful. On a return flight from Perth we had not been informed of an upgrade when we had to leave for the airport and I did not do OLCI as instructed. We waited patiently in line with the other Economy ax and it was only when we were given our boarding passes and checked the seat numbers as we walked away that we realised that we had been upgraded.

Yes I have also always still purchased seats and luggage I just wanted others to be aware that this happens. Air Asia business class seats are significantly cheaper at full price than others, as they are basically a no frills one with a larger seat, so the extra I would have paid if successful would be still quite a large amount.
