weirdly hard to use - missing two key features

I'm representing a non-profit membership organization. Should be a good fit for ChargeKeep, no?
No, It does not do two things which are showstoppers
1. Memberships seemingly only oriented to online business. We need to send printed materials by mail 3 times a year to our members. The online form for payment DOES NOT collect Address1/address2/city/state/postcode. And there is no way to add custom fields to even do that simple thing???
2. For our brand new members we need a BOGO option -- Buy One 1 Year Membership, Get One year Free. There is no combination of buttons that will do this. We could sell a 2-year membership but then it would not renew every 1 year following the end of the first 2 years and so forth and so on
We'll be asking for a refund this week.
