What's going to be done.

Question

I purchased the z2 through vodafone.
It had a faulty front camera, so I got the experia z3
And sent the z2 back to get repaired.
Apparently sony didn't fix it and just replaced it with a brand new one(awesome)
I pick up new handset,get home.charge it up.
For a joke,I test camera..
Back camera doesn't work...
Brand new,not even 2hours old.
So i called my provider, they said go pick a new one up. And I got declined and was told it has to be sent to Sony for repairs...
(it's brand new. 2nd faulty phone in a row. Urged me to upgrade to z3)
And they won't replace it,because Sony has to see it first.(they should have tested it before sending.it. I thought.it's standard)
It's cost me alot of my time. And petrol going back and fourth to sort my phone out.
Yes it's through vodafone.
But it's a Sony product.
And sony makes the repairs and decisions.
How can you not bother to fix my old phone and send me a brand new faulty phone.and sony has to see it first before replacing it again.
3rd time.
I said I don't want another phone now. And they said they can't do nothing until sony sees the phone..
I almost want to return my z3, tell them to stick the z2 and go get a different brand.
It's crap, two faulty phones in a row.
No apologies.
And throwing the blame.
Still a z2 down.
Z3 is awesome though.

If you got your phone via a network then it's up to your network to decide the fate of your phone and not Sony - Your sale of contract is with Vodafone and not Sony - So your 1st port of call is with Vodafone and if Vodafone decline then remind them of your contract of sale and who it's with
