I've got the same problem. Its been 10 days since my first purchase and the only email I get is Order Acknowledgement. I've made 2 more purchase yesterday and today. My developer program is about to expire within days and no contact support could be found. Tried the support section but got error 503 on both call and email request (https://developer.apple.com/contact/topic/SC1101/subtopic/30007/solution/EML/details).
