Your investment in the Alumni program is 100% refundable until the 30 day mark, after which it is non-refundable and the subscription amount will be charged for the next 11 months.  

The Alumni program is intended to hold you to your commitments for a year after you ensure that the product is of good quality for the first 30 days.

If asking for a refund, it is (of course) expected that you have participated in the program fully until that point and have found it to be lacking.
