I have recently switched to AT&T and had to go to the AT&T corporate store at 8031 Concord Mills Blvd, AT&T STORE, Concord, NC 28027.
The staff at this store are borderline arrogant (always on their personal phone, would not answer any queries and act least interested) and the Manager is of no help.
This is the worst customer service ever in my experience dealing with Wireless Companies.
I would not continue for much longer with such atrocious experience.
I have 5 lines with the company.
