As far as I understand it - there is a way for the ISP to delegate the PTR records to you, using CNAME records. But, generally, that's more work than just setting the PTR records (expecially if they just generate them). Regardless, there is nothing you can do about it if the ISP won't do set them, as far as I know. Does you isp have no reverses set? Or, just reverses that you don't like? If the former, they should set them. If the latter, well.. it's just up to them how nice they want to be - but it's certainly not required to let you set them.
