Ok the issue has been fixed successfully. After sending email to contact@btclevels.com They sent me password manually by email.

please dont say this 

Please read the private message i sent to u,

I recently opened an account with btclevels and deposited 7.7btc and a moment later when i tried to login, it says, "incorrect password"  and when i tried to click password reset link, and enter email, i dont receive any email from them, its been 10 hours i have clicked password reset link multiple times and enter email, it says "password recovery email has been sent to u" but i have not received any email, most of all i have sent emails to btclevels support and told them the scenario, i did not receive any email from them. I think they have taken my money and ignoring me now    Please guys, any advice?                              

THE ISSUE HAS BEEN FIXED SUCCESSFULLY, THEY SENT ME PASSWORD MANUALLY. After that i successfully withdrew my money.
