Warning: "STAYZ" accommodation booking site is "SCAM"! 92% reviewers negatively review this "STAYZ" site!

Last October I booked a home-stay at 43 Balfe St, Parramatta Park, Cairns, QLT, through STAYZ (1 Martin Place, Sydney) site, planning to stay for three months (June 1-August).
The site says: they won't withdraw any money from my visa card till mid-May, 2025. However, I noticed that they drew "8,168.70 AUD" on October 7, 2024! (according to NAB's monthly report). Obviously they are "scammers".
Then, I successfully signed the contract of purchasing the property in Atherton, QLD.
So I tried to cancel my booking of this home-stay in Cairns, but the STAYZ system (on line) rejected/ignored my cancellation!
Thus, I shall definitely sue this Stayz scam through laywer(s) to get a full refund, at least!
