Hi.
I can confirm that you don't always get the purchase ID when you buy something. I bought my account some weeks ago, but never got the ID in a mail. I only received the mails from Paypal, and I don't have a spam folder. When you purchase something, the ID is also shown on the webpage. I don't know what you should do to get your purchase ID if you missed it on the website after the purchase.
Feel free to contact me privately if you have something in mind. If you do so, then please send me a mail instead of using the private message on the forum, since I don't check those very often.
