Teavana Inaccurate advertising on website Internet

I received an email on 2/12/15 saying that it was the last chance to receive an order in time for Valentine's Day. I placed the order by noon and paid for overnight shipping expecting that with that advertisement and the fact that I paid for overnight shipping (which is what it is called on their website), that I would receive it the next day (Friday). Any other place that I have EVER ordered from and have chosen that option, I receive it the next day. Anytime I have shipped anything overnight, my clients have received it the next day. I received the shipping notification Friday (2/13) that the package had shipped and when I went to check the tracking number through UPS, I see that it was shipped 2nd day air and that I would not receive the package until Monday - which is completely defeating the purpose of receiving something for Valentine's Day. When I called customer service all they would offer was to refund the difference between overnight and 2nd day air shipping. There were nothing about the fact that they were misleading on both the email saying "Last Chance for Delivery by Valentine's Day" or the fact that the customer even has the option of getting overnight delivery. I have never come across this and  she was trying to blame it on UPS - granted they screw up sometimes but they also take responsibility. Sometimes businesses are actually at fault - so do something to make it right - do something instead of offering the difference in shipping costs. Get rid of the false advertising. This is not how you do business and I will NEVER order from here again. Pathetic.
