Cerebrum IQ Charges Me Monthly Without My Consent, Request Full Refund

I recently discovered that the Cerebrum IQ online platform has been charging my account £39.99 every month without my consent. When I checked my statements in November 2024, I realised that these payments had been taken regularly over the past year, adding up to approximately £440 in total. I did not knowingly subscribe to Cerebrum IQ and I was not aware that any recurring payment had been set up. The charges appear on my bank statements under “CEREBRUM IQ UK LONDON” and similar descriptions, with individual amounts of £39.99. Once I realised this, I cancelled the payments through my side, but I have not received any explanation or refund from Cerebrum IQ, and I have not contacted them directly yet. I do not recall agreeing to any ongoing subscription or authorising them to charge me in this way. I request that Cerebrum IQ investigates these unauthorised recurring payments, explains how this subscription was created, and refunds the full amount that has been taken from my account. I also ask for written confirmation that any account or subscription linked to my details has been fully cancelled so that no further charges will be made.
