HP Tuners & buying credits

I usually buy credits and have no problem with recieving an App Key via email, I use PayPal. Today I bought 2 GM credits using the wife's debit card around 7pm and I still haven't recieved an App Key or and Order Confirmation e-mail from HP Tuners, the debit card was charged though. Is there a cut off time or can I buy credits 24hrs and get my App Key immediately like usual?:hyper2::hyper2::hyper2:

it took about 24 hours to get my app key last time i got some

Mine show up immediately within 2secs literally.
Once I click buy then it confirms I click send receive in outlook and they show up.

Send them an email if it hasn't shown up in a day or so I'm sure they'll fix it

could have also gone into your spam folder.
