shocked homeowner in North york

John Viola, of Sherwood Garage Doors, promised us that his technician will return, without cost to us, if anything needs adjustment wihtin 12 months. Well, it turns out that minor adjustments were needed but Mr. Viola refused to send someone unless we paid him again. He stated, without sending someone to inspect the door, that the problem must be with the manufactuer and therefore he's not responsible. This was his 'profesional' positon? How offensive and sad that Mr. Viola continues to take money from unsuspecting homeowners. Caveat Emptor.
