Bosch Built-In Set Installation Issues – Unresponsive Service

I purchased a Bosch built-in set from an authorized dealer. I showed the seller pictures of the countertop with measurements to ensure compatibility. However, when the set arrived, the service team refused to install it, claiming the countertop spacing was too close, which could cause heat reflection and potentially make the glass cooktop crack. They suggested cutting the countertop, but the contractor who came to do the job said cutting and adhesive installation were not possible, warning of potential collapse and leakage due to heat. Our request to replace the glass cooktop with a metal one was rejected by the dealer.

Now, I’m left with a built-in set that I can’t use, exchange, or return. If the dealer had recommended a cooktop suitable for the countertop's specifications, or if I had been informed about the conditions under which changes or returns were possible, I wouldn’t be facing this problem. Bosch, a brand I trusted for its reliability and which I had previously purchased other appliances from, has been a complete disappointment. Should I sell the unused set at a loss to a discount store, risk damaging the countertop and possibly causing an explosion by forcing a cut, or risk both the cooktop and oven failing? How can I protect myself and my family from potential accidents? Should I throw away the unused set and buy a new one, further enriching big brands while increasing my financial loss? Are you aware of how you’ve put customers in such a difficult position by failing to deliver promised services? If my issue is not resolved soon, I will file a complaint with the Consumer Arbitration Committee and expect a resolution to this prolonged ordeal.
