Buying Premium and Kongregate problem

This isn't really a bug, more of a problem.
I unfortunately connected my Kongregate account with my Afterwind account, and now when I want to pay for premium on AW site, I get this:


And I can't buy kreds on Kongregate, because they don't support my country which AW supports (mobile payment), is there any way to un-connect my kongregate account and afterwind account so that I can pay for premium on AW site?

This is part of the agreement we have with Kongregate, all players registered with us through the Kongregate website have to use their payment options. But as you've originally registered through our website, I don't see any problem with it. Unlinked your account

Thanks.
