Toro Customer Service - HELP

Over 5 weeks ago I brought my Toro model 20093 walk behind lawnmower to a local Toro authorized repair dealer to have a part replaced. According to my dealer work order, the part is described as a "drive bracket for the belt" and is covered under my warranty. I was told that once they had the part the repair would take approximately 1 hour. Well, after 5 weeks and numerous conversations with the dealer and Toro Customer Service, I still do not have my lawnmower. Toro Customer Service has promised action however, the only action I have received is a case number and weekly promises that my mower will be ready "this week." "This week" has been going on for over a month. Now Customer Service tells me "their system is down" and there is no way to check to determine if the repair facility has even ordered the part.

The "HELP" I need is an email address or telephone number I can call at Toro Hq. to get positive action. It's obvious to me that I have to bypass Toro Customer Service. Any other guidance you may provide me would be greatly appreciated. Thanks
