Vodafone deals

[JABB]

Hi all. I’ve been having real trouble with Vodafone and I think finally got sorted but trying to use this issue as a lever to upgrade early and get a deal. They seem very stuck in a trench
Anyone work for Vodafone and can offer any advice as to how to get a good deal?

Looking for a x or xs iPhone with 15Gb + data, no upfront and £42 a month. I can get it, convoluted through fonehouse but Vodafone won’t play ball
