My Battlegrounds Mobile India Account Was Hacked and I Need a Recovery

My Battlegrounds Mobile India account was hacked; the hacker attached their own Google Play account to me, therefore locking me out entirely. I can't access my profile as every time I try to log in I am sent to their account. Worse, they left my account devoid of in-game money after spending 600 UC I had lately. I contacted customer service right away, with all the required information (my player ID and transaction history) but I have not heard anything yet. Having put time and money into this game, I find this to be quite depressing. To get my account back and stop the illegal activity, I urgently need your help.
