Client support sucks

I bought a Whirlpool induction Hob from Hirches 6 months ago it is guaranteed for 2 years, the hob blew up dew to internal problem, now i am waiting 2 week to get a answer from Whirlpool. I must contact then when they promise they will call me back. A week passed i call again they waiting for the technician they said to me, same story as previously. How long should i wait for them, i paid a lot of money. Whirlpool told me they might exchange it but it will take another 7 days is that not wonderful how thoughtful . Meanwhile we cannot cook food, we have to eat take away, sometime prepare food in the microwave. Their service is unexceptionable, i want to get rid of all my whirlpool appliances, everybody should know if they buy Whirlpool product what they are in for.
