WMF Authorized Repair Service Refuses Support for Gifted Grill Without Invoice

I have been experiencing a thermostat issue for approximately two weeks on a WMF model 04 1534 00 11 grill, which was purchased in Germany and brought to me as a gift. The thermostat on the product trips after a very short time, preventing me from using it properly.

When I brought the product to an authorized WMF service center, I was told that the thermostat on this model cannot be replaced separately and requires a full swap, but because the necessary thermostat component is not stocked in Türkiye, there was unfortunately nothing they could do. I subsequently called WMF Customer Service; this time, I was informed that because the item was a gift and I lack an invoice, a support ticket could not be created in their system, and therefore they could not assist me. As a result, a brand-new WMF grill has been rendered virtually unusable and essentially turned into trash.

This product was chosen due to the trust placed in the WMF brand; nevertheless, offering neither a thermostat replacement nor any alternative solution has deeply disappointed me regarding a brand I used to love. I demand that the condition of the product be re-evaluated, and that either an appropriate repair be performed or, if possible, a product replacement be provided.
