I didn't receive a charger either. They knew about the promo at the store but didn't know if it was supposed to come automatically, or you add in basket or it comes via post later lol. They said I've got to ring customer services. Hope it's not a pain get as dealing with CPW so far has been great.
In terms of phone, wow, what a beast. Coming from an s8+ I wasnt sure what to expect in terms of a leap forward. I wouldn't say it's a giant leap but the screen quality is noticeably better, the speed and performance is noticeably better. Everything else I'll determine over time of course but I'm very happy with it.
The overall size of the phone isn't that much larger st all. Very little in it in fact. The weight though is loads heavier!
* in fact just been on the website and can't see the charger on offer with the note 9 now*
