Cancel Nebula Subscription and Refund Unauthorized Debits

I am writing because I am being repeatedly charged by a company called Abbnebula / SGT*APPNEBULA.CO even though I have never made any contract, registration or purchase with them. The first charge appeared on 16.07.2026, and since then amounts are being taken approximately every three days from my bank account, including 51,45 €, 16,19 € and 6,13 €. These payments are taken without my authorization and I do not know what service or product they are supposedly for. I contacted my bank and they closed my card to prevent new payments, but they told me they cannot automatically recover the money that has already been taken. Because of this, I continue to feel unsafe about these unauthorized debits linked to this company. I request that any contract, subscription or account that may have been opened in my name with Abbnebula be immediately cancelled, that my personal data be removed from your systems, and that all amounts taken from my account without my consent be fully refunded to me as soon as possible.
