Gilpin Electrical Repairs

After living without an oven for six months ,I contacted Bosch and was given no of this service. After service oven still doesn't work after being on for half an hr. when I rang to enquire the gentleman informs me nothing wrong with oven,notorious for setting off trip switch. My argument back is the problem existed before the place was rewarded a trip switch capability put inShould have taken my mothers advice replace oven first off,don't waste money on service calls, anyway I have ventilated.i originally rang Bosch and was given the gilpin firm, lucky they don't have excessive repair fees. Played phone message, well sir I had an electrician in as you said,still no working ovenMy point it didn't work even before a trip switch put in. Thanks for wasting my time.trust elect company,they say chuck oven and at least they have it ready for another
