Further update:

To my surprise I called today for the refund and the customer services person pulled up my order and was unable to find any notes as to my previous calls which meant that there was no activity. That explains why I was not called back despite being told that they were working with their purchasers to try to resolve my issue and would follow up with me as to a solution.

In the days since my order I called the customer service three times and also emailed doc my information asking for help.

Looks like TireRack has some work to do in the customer service arena.
