Mennonites operate under an entirely different set of rules, at least those here do. It's also possible that something could be going on that you aren't aware of, and maybe they need the meat gone. They do not tell you their business, but do like to know all about yours.
If it was me and somebody had called me 3 times to come and get something, I'd take the hint and go get it. If I wasn't happy about it, I'd chalk it up to experience and be done using that place.
