Chamet Account Access Lost

I have been using my Chamet account for many months and today I suddenly lost access to it. My old Chamet ID is 72343*** and I was using it on an Android phone. I cannot log in to this old account anymore; it simply does not open. Before this problem started, I logged in on another device through my diamond seller. My number is 7230882*** and my diamond seller opened my ID and added his own number to it. After this, I lost access to my account. On this account I had approximately 43,000 diamonds, which I can no longer reach because I cannot enter the account. I request that my old Chamet account be recovered for me, that my own phone number be restored to the account, and that my 43,000 diamonds be returned and kept safe. I would like this issue to be investigated urgently and my access to the account and diamonds to be given back to me.
