Testora IQ Test Charged Me Repeatedly After a One-Time Test

I recently discovered that I have been repeatedly charged by Testora IQ Test, even though I used the service only for what was clearly presented as a one‑time test. I took the test on May 25 and believed that this was a single purchase, not a recurring subscription. Today I noticed that charges have been taken for approximately the past four months, including a new charge that appeared just a few minutes before I checked my transaction history. Until today, I was not aware that any ongoing payments were being taken, and I had no intention of signing up for a subscription or recurring billing. Since I only agreed to a one‑time test and did not knowingly authorize any ongoing subscription, I consider these repeated charges to be unauthorized. I no longer have any cancellation emails or on‑screen confirmations because I recently cleaned out my email inbox, but the transaction history clearly shows multiple Testora IQ Test charges over several months. I request a full refund of all charges taken over the last four months, the immediate cancellation of any existing subscription or recurring billing related to my account, and written confirmation that no further payments will be taken from me in the future.
