The rep credits the accounts. There is nothing you need to do except wait for him.Do they apply the code or is it something we need to input ourselves when the time comes?
They do have up to 72 hours to credit the accounts so at this point, he's not late. But note... there have been times crediting happened after 72 hours. It depends on how busy they are. But also note... this particular rep credited winners within an hour of receiving my winner's email a few contests ago.
If I don't get a reply to my winner's email from him today, I will email him again later on today.
