Zety Unauthorised Charges

I am writing to raise a serious complaint regarding unauthorized subscription charges made by Zety to my card. Without my clear consent or awareness, Zety has been charging me every month since October 2024, and the total has now reached almost 700 dollars. I only recently discovered these ongoing debits and immediately contacted Zety customer support. Despite the fact that the subscription had been billed for around nine months without my authorization, Zety only agreed to refund a single month, which I find completely unacceptable given the size of the total amount and the duration of the charges. My Zety account is linked to the email address limchi***@gmail.com and I am based in Singapore. I expect Zety to review my case properly and issue a full refund of all unauthorized charges taken from my card since October 2024, not just one month. I also request written confirmation that my subscription has been cancelled and that no further charges will be made to my card. I ask that this matter be resolved promptly and in good faith, as the current response from your support team does not reflect fair or responsible customer treatment.
