Wow, Never expected scamming from you Apple.
I had a microphone issue, So I submitted my iphone 13 to a apple service centre.
After a week, I got a call, The service centre guy said that There has been an abuse in my phone's internals (It was so vague). I raised my concerns with apple India, They said they will look into it.
2 days later I got a call from Apple, Saying that my device has been modified by third party (I have never given may phone to another person for a day let alone a third party repair shop). I mean if you don't want to repair my device under warranty just say it, Don't lie to my face. Pathetic, Never expected this from you Apple.
