Amazon ps4 card code not arrived?

Just bought a Ps4 card with a code for my son. I've done it several times and the code always came via e-mail, but strangely enough, no code was received but this message. What does that mean?

Go to the purchase email it says how you get it

Where can i find the purchase email? Didn't get any emails about the order

Then the purchase has not been completed

But the money was withdrawn
