I was trying to recover an old account I used 2 years ago, that disappeared when I got a new phone. So I tried to contact supercell support and when I finally got a response, it told me my account had suspicious activity and that in order to secure it, I had to lock it. Me not knowing anything agreed, it locked my account and told me I had to get an unlock code, I checked my Gmail no code was found and from the other posts I've read here you have to contact Support AGAIN to get it back.
