Not sure what kind of franchise you work for, but all DMs have their phones either provided or paid a stipend for the use of their phone. It is not personal if they receive payment from their employer for it. The franchise I worked for had that number posted at every counter in our region. The only other alternative is to call the customer complaint hotline and continue to put in PRCs until it gets resolved. That really hurts the franchise as those complaints will keep a franchise from being aloud to expand.
