Win back a client who left on price

Act as a producer writing to a client who left on price a while ago. Write one paragraph that gives them a reason to pick up the phone.

Client: [NAME] · [WHAT THEY HAD WITH US] · left [WHEN]
Why they left: [THEIR WORDS, IF YOU HAVE THEM]
Where they went: [CARRIER OR AGENCY, IF KNOWN]
What has changed since: [OUR MARKETS / THEIR SITUATION / RATE ENVIRONMENT / NOTHING]
Channel: [EMAIL / TEXT / CALL SCRIPT / LETTER]

Produce, in order:
0. ASSUMPTIONS. Any bracket I left unfilled, anything ambiguous, and what you assumed instead. Write "none" if there were none
1. The message. Under 80 words
2. The one thing that changed, stated plainly. If nothing changed, say so and do not send
3. What NOT to say, specifically about why they left
4. When to send it relative to their renewal
5. What to do if they do not answer
6. WHAT I ASSUMED ABOUT WHY THEY LEFT. Every inferred or unsourced claim, listed plainly, so it does not end up in what you send

Rules:
- Anything you inferred rather than were told goes in "WHAT I ASSUMED ABOUT WHY THEY LEFT" instead, never in both places
- Never say we told them so, and never reference the old price
- If nothing has actually changed, the output is "do not send this yet" and why
- No guilt, no nostalgia, no "we miss you"
- Hard limit: 300 words for the whole response. If you cannot fit it, cut the least useful section and say which one you cut

Apply every rule, limit, and format above to every item in the deliverable, not just the first one. Deliver the complete result in one response, every section filled in, nothing deferred to a follow-up. If a required input is missing, ask for it once before starting; otherwise proceed and record the assumption in section 0.
