Customer service is not their forte.
I upgraded my phone and purchased a Mac Book Air. Upon leaving the store, I was sent away without the box for my phone (no charger, no instruction manual, no ear phones.) I didn't realize until I got home and unpacked my bag that it was not there.
I called a day later to follow up and luckily they had it - but hadn't made any effort to contact me? No apologies either, which was a little disappointing.
