Defective product and no service

I bought now all 3 Licking 3 Solar mats after a year to every nook and cranny.
When I got in touch with the service I received on normal emails no answers but only one-line sentence fragments, my questions were not answered.
Then I sent at his own expense a mat.
After 3 requests on my part and 6 weeks later again a one-liner that I could pay 34 euros for the repair (plus shipping).
What was the result and why it was my fault the unjustifiable void the warranty of course was not mentioned.
Once I actually had someone in line at the 5th call was explained to me that the technician that can already judge and to the question what would you have found the answer that there was indeed an opinion a few hundred euros would cost and I therefore do not expect the Koenne.
Mind you, I just wanted to know for what reason I was denied the guarantee.

Conclusion - bad product and catastrophic service - never again Elecsa.
