I Got a Faulty Delonghi Magnifica Start ECAM220.22.GB and Now I'm Left Without a Replacement

I recently purchased the Delonghi Magnifica Start ECAM220.22.GB fully automatic coffee machine, and it malfunctioned after just one or two uses. When I contacted the seller about a replacement, they refused to process it without a service report, claiming the product had been used.

I delivered the unit to the authorized service center on March 8, 2025. Today, I was informed by the service that a replacement couldn’t be issued because the same model is no longer in stock. They told me I could return it to the seller instead. But here's the issue: why am I, as the customer, expected to absorb the consequences of product unavailability? I want to know—isn't the company obligated to provide a higher model if the original product isn't available?
