Culturally C.

I purchased a Polk-Audio sound bar at the Best Buy in State College, Pa on Jan 31st, 2015. The very first day I started having problems with tuning it off. I had to unplug it to turn off. Since then it will only turn off some of the time. So yesterday February 7th I stopped by the store to ask about it. That's where the problem started.
Don't get me wrong the sound bar has a fantastic sound by the way. The sales person said that he would have to talk to his manager about holding one for me because they here all sold out.
The manager told him to tell me that the only way they would hold one for me would be that I would have to pay for a new one first. What king of business is that? I just paid over $400.00 last week for one.
I have never in my life heard of such a thing. I'm very close to saying that this is a racial thing.
It's not the first time I felt singled out in this store.
The first time I walked in the store I saw a employee that obvious was not a sells person look at me and radioed someone that came rushing up to me immediately asking did I need any help. This person also was not dressed like the other sales people in the store. I sort of forgot that incident until yesterday.
I don't believe that anyone should have to pay to have a product held for you due to a product defect that you just bought.

I would love to hear what head quarters thinks about it. This can not be a store policy and if it is it sucks.
