Overall the techs do not communicate what is wrong with the equipment., where they are with a project, and don't fix issues at the appropriate level. Total bill for location was over 3000 on an oven that is still broken and 25 years old. If the damage was irreparable, then they should have consulted prior to spending that money. We are actively looking for a more qualified repair partner.
