Tineco Floor One S3 Error – Repair Cost is Unreasonably High

My Tineco Floor One S3 vacuum started showing a service error, even though I’ve only used it around 30 times in three years. It was mostly kept in my summer house, so it has barely seen any wear.
I sent it to Tineco service last week, knowing that the warranty had expired, and requested a paid repair. However, today, I received a shocking quote of ₺4600 for the repair—on a vacuum I originally bought for ₺7500!
This is completely unreasonable, especially since this issue appears to be a common defect—I've seen at least 8 out of 10 people report the same problem.
