what is the address for exchanges and returns?

[7Gemma77]

I received no confirmation detail, returns packaging and any information on how to exchange or where to send a return.

Please can someone let me know how and where to send a return/the address, or better yet, how to exchange my iphone  - keeping in mind that I have not been sent a returns, a confirmation email or even a proper receipt.

You need to contact O2.
All numbers are in this guide Guide: Coronavirus Community Help and Support 
Or 202 from your O2 mobile.
Advice from an O2 Guru to get through:
When you call 202, you will be asked for the reason you are calling.
Stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
You can also try saying "Upgrade" or "Fraud" to be connected to an advisor.
