Hi. I had an iPhone 8 plus is great condition. I took it in for a battery repair and they told me to wait an hour. I went back and they told me that during the repair the Wi-Fi module was damaged but they were not sure if it was their error or if it was broken when I dropped it off. They gave me another iPhone 8 plus. I examined my old phone and the Wi-Fi symbol was on and working fine. My question is why didn't they just replace the Wi-Fi module, he said they couldn't because it was built into the enclosure of the phone. I know I should complain because I got a refurbished phone but I still don't trust refurbs.
