Extended warranty is a **** and no concern for after sales service at all

There is no after sales service from Hirsch's. We purchased a Whirlpool oven which has had two repairs under warranty as the oven just changes cycles on its own. The same part replaced twice. The same fault. This is the only and last item we ever bought from them and had purchased an extended Hirsch's warranty and the VERY SAME fault occurred again. Our oven was taken away and the fault was not even replicated in their workshop and they wanted to return it... no repair.. sent it back, and then was told the installation was the problem but they could not say why and would not assist with an installer even though we were willing to pay as we did not believe them. We were told it was ventilation issue and the oven is over heating and so we further cut out the cavity to accommodate this stupid request as they advised and guess what, we were right, The very same fault is occurring and from start, i.e. the oven is cold... escalated to Luci Jackson (nee Hirsch), who couldn't care less - so much for a "family" business. Such **** artists - deal with them if you want to get your blood pressure up as you are only assured frustration in your future.
