Horrible
When I was there there were two employees, one who didn't quite know what to do, and the other one, who knew exactly how to do what I was requesting, but couldn't be bothered to walk around the corner to show his co-worker. He spent the entire 20 minutes I was there with his back to me, refusing to answer his co-worker's questions about how to proceed. He wasn't busy, there were no other customers the whole time, but he spent the entire time with his arms folded, checking the screen on his phone. Obviously, he wasn't interested in my business.
Oh, and he lied about the service charges for the changes I was asking to be made, it cost me several hundred dollars in charges that it took days of calls to customer service to be reversed.
