Query: Defective product

I used Strivectin several years ago and really liked it. However, my recent purchase through 101BeautyStore was less than satisfactory. The product I received was old. Strivectin turns a tanish brown color when it is old. There was no expiration date ANYWHERE on the product or the product packaging. My rating is actually for the seller and the product I received not Strivectin as a whole. I followed the proper procedures for reporting the defective product to 101BeautyStore and they never responded. I then contacted Amazon, took the proper steps and am happy to say Amazon was fantastic in refunding my money in a very professional and courteous manner. I will defintely still shop on Amazon but will not purchase from 101BeautyStore.
