Hello! I am Tanay Rajoria! I really need some help.
I gave my android phone to a repair shop few days ago.Now when i received it and started playing clash of clans i noticed that there are new attacks every day which i don't do and many changes in my base.Sometimes there are attacks and sometimes changes in base and also new chat messages.
I changed my Google+ account password which is linked to my clash of clans and also the GameCenter account password.
Your only option is to use the in game support and email support.
explain the problem fully, send the email. You will receive confirmation with a unique number/case number and then it's just a case of waiting for support to get back to you.
