I have used att for a few years now, and recently had a problem on my iPhone 13. I contacted them and said they would send someone out immediately, as it was under warranty. Now two months later, I am being charged $250.00 for their service. A fee was never mentioned, until I received this invoice notification. I have nothing good to say about ATT, and their warranty or service. I will be dropping them, as soon as possible. DO YOURSELF A FAVOR AND NEVER USE ATT FOR YOUR SERVICE. YOU WILL EVENTUALLY REGRET IT. Terry
