Z3 camera flash beed problem after service Sony denied to replace or repair

[Apaar]

Hey guys my 2 week old Xperia Z3 has been in repairs for past 45 days (due to static on the screen) now when i get it back there is a problem with the camera as you can see in the attached photo.
Whenever flash is used the photo turns out to be like hazy and blurred I figured its flash bleed problem because the back glass has not been installed correctly by xperia care which also makes my phone non water resistant because in the service menu the preassure sensor does not show change when the phone is squeezed.

Now when I contact local Xperia care they kept the phone for 5 days did nothing but update software and gave it back to me but the problem remains, they are just not willing to replace the glass back or provide a replacement phone (they just say it is working like it should even when they look at these photos) I get a reply "Sir there is no hardware problem with the phone flash makes photos appear like this" seriously **bleep**! what am I supposed to do now? What is the use of Warranty when you cant fix a simple problem or provide a new replacement phone? I have not got a chance to use my brand new Z3 since past 2 months. Its a real shame because now Z3+ is out making my phone dated.
I've owned almost all the Sony Xperia flagships starting from X10 this is the first time I've had any problems and Sony isnt able to fix it! Is there someone senior from Sony who I can talk and explain my problem to? Can someone here help?

Does your phone has a protective case and/or film? (on the back)

could you post a picture of the back of the phone near the camera?

[Apaar]

Hello uliwooly, there is no protective film or case on my Z3's back, neither there are any scratches on the lens.

Could you take a close up of the camera lens and flash? thank you

Few photos near the lens.

Please suggest what I can do since local Xperia care team dont seem to understand a simple flash bleed problem...

The ring of the camera looks odd, it seems as if it's coming off, it's supposed to be flat with the back panel

I read somewhere that someone who had a similar issue took a black pen to the silver ring and coloured it black which fixed this issue - I'm not saying you should do or try it but I did read it somewhere
