My Clash of Clans Account Hacked, Negative Diamond Balance Not Resolved

A few years ago, my phone was stolen and my Clash of Clans account was on it. I didn't think much of it until I tried to log back in in 2022 and saw that my in-game diamond balance was showing as negative 60,000 diamonds! Despite playing for a year and earning diamonds, my balance keeps dropping into the negative. As of now, it's at negative 54,731 diamonds. I've sent multiple emails and contacted support, but have not received any response or help to resolve this issue. This is my original account and I have put a lot of time and effort into it. I'm hoping someone can help me fix this negative diamond balance issue as soon as possible. Thank you.
