Refund Z3 Roxfit Cover

[Anonymous]

Hi everyone. Now i have the xperia z3+,but before I have the z3,which was dead without reason and so the guys from assistance change it with the z3+. Now the problem is that i had a roxfit cover, bought from online shop o2,for the z3 and obviously it is not compatible with the z3+. A week ago i send the cover via royal mail to o2 returns center, hopping that i will be refunded or they give me a z3+ cover, because wasn't my fault that i change the phone. Still now i'm waiting for a response from them.
The manager of the Wigan O2 shop told me to send it via royal mail and it is possible that they will change my cover. I send it with all documents to show that everything is ok.
How can i proceed now,because i want to know what is happening with that cover now...
Thanks in advance!

You'll have to ask CS what is happening next http://www.o2.co.uk/contactus

Did you send it recorded or registered requiring a signature?

I've send it with the label that is included in the box when received from O2.

Then the only option is to call to see if they have received it or wait until they contact you. There is no other way of tracking it.

As I said at the start - no other way unfortunately.
