I've previously done the One Account favours by telling people how happy I was with the service. I'm sure they have had good business due to us. Like people here though I feel like they are breaking a promise with regards to the tracking the base rate. I'm going to join the crowds and write to them tomorrow to demand my 1.5% cut and express my willingness to move mortgages. Maybe a letter explaining that I believe them to be in continuing breach of contract will at least get a proper letter of explanation from them. I've considered for a while asking the dozen people I know with the One Account if they want to sign up to say cut it or lose us. In total a couple of million in business should be more of a factor for them than just one or two grumbles.
