Fakir Upright Vacuum Warranty Repair Fee Dispute

I purchased a Fakir upright vacuum and sent it to service twice from Konya Selçuklu due to a broken latch and a noticeable loss of suction power. Although the product is within the warranty period, both service centers demanded a fee for the repair and did not stand behind the product as I expected. In both service applications, I clearly stated that the problem was the broken latch and reduced suction performance, but despite this, I was told that the repair would be chargeable. I am not satisfied with either the product or the after-sales support I have received so far. I clearly request that this unfair fee demand be cancelled and that either the product be replaced with a new one or my payment for this vacuum cleaner be fully refunded.
