Problem with a gift card

On saturday i bougth a 3 month subscription gift card and chose pdf to download the code (I was using my mobile phone to do this purchase). After payment chrome got stuck and i couldn’t watch the link to download the pdf. Even chrome restarted the window but there wasn’t the link to download the code.
I have the email receipt with id transaction. is there anyway to recover the code? is it possible to recover the code by contacting support team?

Thanks in advance.
