T-Mobile at 4937 Telegraph Avenue Suite C, Oakland, California.

Technology sector has T-Mobile as they friendliest provider out of the four US big players. Maybe the article meant online chat or call center. I was in the place at least seven minutes went by before being greeted. At this point I didn't want to bother them since they didn't asked what I needed earlier. Pick up couple of phone and mess around with them. My intention was for them point out what's the biggest advantage they've over the other three. I left without making a purchase.
