I also must say that I do not think you will ever find great customer service at big box stores like these. I ended up going to Best Buy to get a radio installed and am not having much better of an experience.
Basically from the time I walked into the store to the time I left I was dealing with a bunch of people who didn't know what the hell was going on and continuously passing the buck. It baffles me because I went in there willing to throw money at them but nobody seemed to care much. I don't really blame them. It sucks working in retail.
I was double booked at 2pm (after getting shafted at 11am). Installation guy asked if I could come back at 5pm (which I could have but didn't want to). Asked him what time my truck would be done if I did bring it back at 5. "Uhhhhhhhh I really couldn't give you a time, man." That did it for me. I walked out and got a refund.
I will not be returning. This store is a joke most of the time. I can't remember the last time I walked in and was approached to see if I needed help. There always seems to be a lot of staff around, but they're usually chewing the fat with coworkers.
