Bad Customer Service

I went to Musica Mall of the North store on Tuesday with my children looking for Alvin and the Chipmunks 2 DVD. I enquired with one of the sales persons at the store who informed me that there was no Alvin and the Chipmunks DVDs. I was not happy with the way he quickly dismissed our request so I told my children to look through the pile of DVDs available. After 15mins, we found Alvin and the Chipmunks 1, 2 and 3. I told the salesperson and he just said he did not see it on the system. Today I went again to Musica Mall of the North looking for Justin Bieber's Believe DVD and I found the same salesperson and I asked him if the DVD is available and again he just went into some back room and came back in 10secs and said there is no Justin Bieber in the store. I decided to look for myself, again to my amazement I found the DVD after 10mins of searching. I immediately went to the same salesperson and reminded him of how he told me there was no Alvin and the Chipmunks and now again he told me there was no Justin Bieber and I found both DVDs. He responded by saying \that it is not my problem as the system told him it was not there.\" I can't believe Musica employs people with such attitude."
