I'm not receiving the code

I have another account, kael1233. I have the email address and I've been playing with that account for about a year. Today I tried to log in, but I haven't received the code to access the game. I've tried from the website, and it asks for the code, but I haven't received anything. I've been trying since this morning, and I'd like to know if I'm doing something wrong or if I can recover it. I lent it to a friend, but never with the intention of selling my accounts, as I'm attached to them and have even put money into them. Please help, I need to know if something happened to my account.
