I'm try and get through to them but they are not taking calls. Thanks

Thanks so much, I know terminology can be tricky with people like me not well up on it 

Ps it is my own phone, and existing SIM, I had applied for an upgrade to it that's all, no physical product to return

Hi I don't have a physical product to return, just don't want the upgrade ?

Hi, I can see that there is a policy for change of mind in upgrade, but can't find where to do it, and they won't let you ring up now. Any clues anyone? Thanks
