Currently paying £23.25 a month for M125.
Called up to cancel, the automated system offered me £6 off each bill for the next 6 months. Then would rise to £44.25 PM 😭.
Ignored that and spoke to a agent and he asked if I've made up my mind or if I wanted to see what he could offer.
He offered me £23 for the next 18months with the RPI rate not affecting me either.
Pretty happy with that result
