Renewal notices make more sense when the previous invoice and the new offer are compared side by side. I’d check whether both cover the same service period, whether an earlier promotion ended, and whether the quoted amount is for the same subscription level. The current service can stay out of the discussion because nothing has changed there yet. At that point, I’d reference the dispatch phone number once the two documents are summarized clearly. I’d ask only what changed in the renewal terms and keep the question away from general billing, since no new charge has been made.
