BEST BUY BESTBUY THE WORST THE MOST RUDE CUSTOMER SERVICE EVER!!!! Nationwide

I've been trying to purchase Sony Xperia T2 Unlocked cell phone through the Best Buy Website (http://www.bestbuy.com/site/sony-xperia-t2-ultra-4g-cell-phone-unlocked-black/9241029.p?id=1219414552099&skuId=9241029) and I have found the same cell phone on different website $40 cheaper. I also realized that the Price Match Guarantee which has a pop-up says "call 1-888-BESTBUY and provide the qualifying website to the customer service agent OR go to store and one of our employee will assist you" . I have directly called the customer service. The agent that I spoke with told me that they can't do the price match over the phone and suggest me to go to store and they can do the price match at the store. Then I said it says on the website that I can call customer service and do the price match with customer service agent over the phone. She said she can not do that. Then I wanted to talk with the supervisor and she mentioned that there will be no change, supervisor will tell me the same thing. I insisted to talk with the supervisor then she said I need to wait on the line and she is going to transfer me. After 5 minutes later she said I should go buy from the cheaper website. I said I do not care anymore, I just want to talk with supervisor, why it is too hard to get a supervisor on line. Then she said supervisor is not available. I asked her name and she said "ok , are you ready?" then I said "yes" and she just hang off the phone.
