Guitar Center, Villa Park review: Shipping

Recently I ordered online a used Fender P bass from Villa Park IL store on a Thursday. I called first and spoke with competent/friendly employees. I was expecting this instrument to ship the next day (Friday) and I paid for overnight UPS shipping. The employee assured me that I should get it the following Tuesday with MLK Day being on the Monday before. I contacted the store on Tuesday (the day I expected to receive the instrument) only to find out that it is still sitting in their shipping area/department. It did not ship out as expected the day after my purchase. I'm disappointed in not receiving the instrument when told by Guitar Center and UPS. Mostly, I feel that I wasted good money for overnight shipping when I am not receiving overnight shipping. What do I want? I want a refund for the shipping and a pack of D'Addario Bass strings. Will this make it right? No, but it will go a long way in restoring my faith in Guitar Center. I'm a university guitar professor who, at this point, plan to share my misfortunate experience with my students. I'd prefer to share with them how Guitar Center made amends for their mistake.
