The easiest way to do this is opt in to marketing communications and then just phone up and go straight through to the I want to leave part. In my experience you don't get to speak to anyone useful when you call them so there's no point in having a discussion with them.
Put that in motion and at some point a few days later someone will phone you to offer a deal.
My last renewal took about 20 minutes: 15 minutes on hold before I said I was leaving and then a brief call when someone called me and asked what I wanted to stay.
start the leaving process first, wait for them to call you back
Did that a few months ago. Ended up with £35 a month for their 500mb service and £16 on O2 for unlimited phone/texts/80GB data. then did the Virgin/O2 boost thing to bump to 900MB and 160GB data for same price.
