Query: GREAT CUSTOMER SERVICE

I ordered this perfume and said i needed it by new years eve because i was going to be going out of town. (it was during the holiday season so i didn't know if it was possible) they assured me if i did the higher delivery it would be here in time- well UPS messed up and didn't pick up my package to deliver from their warehouse. I called them when i noticed it hadn't been shipped and they OVERNIGHTED another perfume to me to make sure that i had it when I was supposed to, and to just refuse the other package when it came- WELL i was out of town when the other one was supposedly delivered and never had to deal with the second package. GREAT CUSTOMER SERVICE A+++++++ WILL DEFINITELY DO BUSINESS AGAIN!!!!!!!!
