Before contacting Support, try restoring your progress automatically: https://zepto.helpshift.com/hc/en/3-king-of-thieves/faq/98-how-do-i-restore-my-progress/
 
We have prepared a set of rules regarding account restoration.

1. You can restore the account manually via the Support Team only once in 3 months.
2. If the account was lost again within 24 hours after restoration, it can be restored one more time (but not more than once).
3. We restore accounts only to those thieves whose level was 21 and above or those who made purchases in the game.

Please note, that you can only have one account on one device. The Support Team has a right to decline your restoration request for any reason.
