Bill, that is poorly worded.
It sounds like you don't get a refund if you don't get the insurance.
But the way it's worded, you don't get the refund even if you get the insurance.
I think the intent was to give a refund if you get the insurance, but the contract is governed by it's text, not by what you think it means.
They need a better lawyer. (or whoever wrote the dang thing).
If they tell you on the phone you get the refund if you get the insurance, but if you sign that contract (as written) the deal is governed by the contract, not the phone call. See the Parole Evidence Rule,
https://en.wikipedia.org/wiki/Parol_evidence_rule. It precludes parties who have reduced their agreement to a final written document from later introducing other evidence, such as the content of oral discussions from earlier in the negotiation process, as evidence of a different intent as to the terms of the contract.
Only sign a properly corrected contract. Of find another rental.
