Bitdefender Subscription Ended Early Through Musiclover Without Resolution

I purchased a Bitdefender subscription through Musiclover, which was supposed to be valid from 17/09/2025 until 17/09/2026. However, on 26/05/2026 my Bitdefender subscription stopped working even though the end date had not yet been reached. After the interruption, I contacted Bitdefender support, and they informed me that the issue was related to Musiclover and referred me back to them. I then submitted a complaint to Musiclover on 26/05/2026, but I have not received any response so far, and my service remains unusable. Because I have been unable to use Bitdefender for the remaining period of the subscription, I request a refund from Musiclover for the unused period between 26/05/2026 and 17/09/2026. I kindly ask that this issue be reviewed and resolved as soon as possible.
