We called Service 4 Appliances to repair our Double In-Wall oven. The tech arrived on time and prepared to diagnose the problem. He told us we needed a part that he would have to order. He said the cost of the service call and to pre-pay the labour for the installation of the part was $295. But they couldn't get the part and wouldn't refund the portion of what we paid. It took me three weeks of calling them and not getting a call back to establish this. I was told that managers don't speak to customers and there is no way to get in touch with one. So I am left with the bill, the wall that was scratched up and the broken molding from the work the tech did.
