Just thought I'd share my nightmare service saga with you all. NZ OnePlus fans take note!). When I received the phone back, they had scratched the side of the aluminum rear panel near the alert slider.

 

Some might remember that I had issues with my 3T camera not focusing. Since I purchased it from a reseller locally, I contacted them to arrange repair/replacement. They eventually agreed to replace the camera unit. When I received the phone back, they had scratched the side of the aluminum rear panel near the alert slider.

 

I again complained about this and, after a lengthy email chain with photos of the damage, they agreed to replace the rear cover. At this point, whilst it had been a frustrating journey, I was quite happy with the reseller's efforts to remedy the entire situation.

 

Last week I finally got the phone back, took it out of the box and boy, did it look brand new. But something didn't feel quite right. Usually the phone is quite cool to the touch... The back of the phone felt different, the logo didn't look as crisp as before. I tap the rear panel... its plastic. Cheap, trashy plastic...

 

I've already contacted the reseller to express my horror, frustration and pure outrage. Now I have to wait for a response.

Later in the comments:

Unfortunately it is PB Tech. Fingers crossed that your phone has no issues during your ownership.
