Small business program approval

How long does it take from applying to the Small Business Program to getting it confirmed? Google has a similar program and that whole process took two days. I’ve been waiting for over a month now without recieving any confirmation, information etc. Nada. Wrote to the Apple support and got a generic reply that didn’t really answer anything. It is soon time for a payment from sales and it’s getting really frustrating. Do Apple pay back the difference retroactively?
