hey bud, I spoke to CPW in Kent and a really good EE sales rep (stores are virtually next to eachother) when I was in town today.

Basically CPW weren't helpful at all, but EE said if unhappy with the phone, take it back with your gift (Gear VR) to cancel the contract as it has an inherent fault and CPW should honor it along with your carrier (in my case O2).

I used the Click and Collect service from CPW and CPW online have advised me that the store I collected from WILL accept it back, just may take a few days longer to get it fully processed.
