Negotiate a Better Deal on a Regular Service or Subscription

Your broadband, insurance or phone bill crept up while you weren't looking, and the loyalty discount went to new customers instead. Tell it the service, what you pay and how long you've been a customer, and this hands you the lines to use, when to ask for the retentions team, and where your leverage actually sits. For anyone who hates the phone call but wants the saving.
