Sears / can't get sears repair to fix

They can't repair my stove either. We had the same tech guy come 4 times to my house and another guy once. Both told me to contact the store to replace it and that they both can't do anything about it. When I call the store and the insurance, they tell me they need the tech person to determine whether or not a replacement is needed. If so, the person will sent the notice to their company to approve the replacement. Plus, they kept sending the wrong parts of my stove. Its so frustrating.
