Walk Behind Lawn Mowers

What is the direct phone number for Husqvarna? The 1-800-487-5951 number is useless. I ordered a part at this number. I was told 3-5 days-it is now day 10!! I called them and was told it is on back order. I could have ordered from my local dealer and not waited this long. I called the 800 number again as I felt being Husqvarna this part should be in stock, I was not allowed to speak to a manager if they even have one. It sounds like all they do at this number is take orders. They could not give me the number to Husqvarna. I need the BOTTOM BELT COVER MODEL# 5521CHB. How can I contact Husqvarna???
