Business ProfileforSteve's Appliance & Furniture

Purchased a Bertazonni Double Wall Oven (Model PROF30FDEXT) ($5379.45) on 3/3/2022 (invoice # *****). Picked unit up in May, Steves Appliance could not give a deliver date, waiting to schedule when something else was being delivered in our area, so I installed it on June 5 following all manufacture instructions. There was no discount for self-installation or pickup. Assured high quality for price and very rare need for service. Was told the service department was great and would support the unit in timely manner if needed.On 6/9 baked brownies and were not cooked inside, temp was 50 below setting. Reported issue to store and requested service, was told they would schedule when they had other service in area. Advised they would check on calibration process I could do and get back to me. Owner called on 6/11 reported still waiting for information. On 6/15 got text stating ordered thermostat and would schedule service when it arrives, could be a few weeks. No other calls from the store to date. I have called them repeatedly. Now state that a switch is in, but temp probe is not, supposed to do tracking on shipment but will not call me back. Internal temp does not reach preheat when alert states it has, also it fluctuates as much as 75 degrees from setting, up and down during cooking. I have requested a technician multiple times and they refuse to send one. A lot of blaming others for the problems, from federal energy compliance regulations to no service training or schematics from the manufacturer, they tell manufacture what is happening and are sent the needed parts, do not do service call prior to parts coming in. How can a problem be diagnosed without looking at it, could be as simple as a loose connection?We are looking to have the unit returned to the store for a refund, it has not worked correctly since installation. We do not want store credit as they refuse to service what they sell in a timely fashion, full of promises with no action!
