how come im a member but I cant buy my points back for free
Unlike some of the member benefits (eg bigger backpack, longer friend list, faster energy refill etc) there are some member benefits that are time limited and we have to wait for them to come round (eg double pet XP, double gardening, free training point buy-back etc).
The good news is that the birthday month is almost here and KI usually put on a lot (all?) member benefits at the same time to celebrate another year of the Spiral.
I'm not sure why your thread is titled Mr Wilkins, maybe I am missing something, but you need to see Mr lincoln in Golem Court to buy back your training points
