Query: Frustrated for now...

I cannot give a good review yet because I received the unit without all the parts. When I called the 800 number on the operating manual, I hear, "I'm sorry. The extension you are calling is not available at this time...." yada yada. So how do I get Amazon to send me the parts? I don't want to send the whole unit back. I just want the L-bolt, carriage bolt and nut. Hmmm. I think I will go to my local bike shop tomorrow and see what they can do. I paid for expedited shipping so I would be able to set this thing up on my first available night off...(I work nights) and get my program going. So, hopefully Amazon will make this right quickly. I'm just not sure how to get the right person's attention to get it taken care of. When it's corrected, I'll write a revised review.
