Laser Clinics Australia - Rouse Hill Town Centre

I purchased some pre-paid laser hair removal packages and a facial laser treatment, totaling over $600, on April 14th 2023. I had two treatments done and when I went back to book a third treatment on April 20th 2023, I was told that my pre-paid packages had expired 6 days earlier on April 14th, only 12 months from the date of purchase. I was shocked and told the girl that I was never told that there was a 12 month expiration date on the pre-paid packages. She said that it was in the customer contract that I signed on the day of purchase. I asked to speak to a manager and was told that no manager was there and that she would get a manager to contact me the following day. The next day was Friday and no manager contacted me. I phoned and asked to speak to a manager and was told the same thing, that no manager was there and that she would get a manager to call me on Monday. On Monday, no manager contacted me, so I phoned again and asked to speak to a manager. This time I was put through to Ash and I requested an extension on the time period to have my pre-paid treatments. She told me that she could only offer me one laser hair removal treatment "in good faith" and that I would have to forfeit the money for the other pre-paid treatments. She also said that the pre-paid treatments had "fallen off" the system and were no longer visible. What I don't understand is how a business can take a person's hard-earned money in exchange for a service and put an expiration date on redeeming that service? The owner of the franchise has my money and has used it to support themselves without providing me with the service that I paid for. That's theft in my books! I phoned the Department of Fair Trading and was told that I had grounds to submit a complaint, which I did, online. However, with a current 10 week waiting period before complaints are even being looked at, I doubt that anything will come of it. A very hard and very expensive lesson to learn on my part! Something needs to be done about businesses ripping customers off in this way, as it was done when the expiry date on gift cards was extended to 3 years in 2018. All I'm asking is that the expiry date on the services that I have already paid for is extended so that I can redeem those services. In what world is that unreasonable?
