AT&T review: Management

My phone broke so I made an app't at ATT in Goodyear for 10AM. I walked in at 10:03 and the customer rep said that they were helping another couple. I'd been to this store before and with only two reps, I waited almost an hour before walking out. So I asked if the customers had an app't and she said, No, but you are late so we always take first come, first serve. I asked for a manager because I was under 5 minutes late and the manager came out. I told her why I was there and she went to look up my account. She said I needed to calm down or she would not help me. I started to talk barely above a whisper. I did not challenge her even though I was not being loud or assertive in any way. just annoyed. While looking up my account, I then shared how my phone would stop working around 4:30 every day, and until after 7 pm. . She said she had never heard of ATT doing that. We were sitting at a table and on the table was a sign that read, ATT will lower speed service if too busy. I pointed out the sign to her and she told me quite rudely that I had better stop my derogatory conversation. I shut my mouth until she finished helping, and for all the time it took she just handed me a phamphlet and said she can't help in the store.
