My job sheet no is ggn3965421. I had sumbmitted iphone 7 plus in cyber city support on jan 16. There was screen blackout issue and voice issue. First, i went there on 15 tey did ios upgrade and said its solved. On 16 again i went they submitted it, on 17th they said collect it, when i went there issue was still there in front of them, again they kept it and now saying it will be sent to bangalore for repair and we will take 3 more days.

I have bought phone 2 months back and there are too many repairs. I want new phone from apple to avoid same issue in future from same handset. I am very old user of apple but this is first time i am very frustrated with apple services.
