Garena Free Fire Account Recovery via Original Device Hardware ID

I have a serious problem with my Free Fire account that I created around seven years ago and I would like your help to recover it. I had been playing since approximately the 8th or 9th Elite Pass, and over the years I spent around 2,000 (which was a very big amount for me at that time, around ten thousand in my local currency). This account was very valuable to me both in terms of money and time invested. Around two or three years ago, when I was still a kid, someone somehow got access to my Free Fire account without my permission. They changed the ID and password, and since then I have completely lost access to the account. At that time I did not know what to do, so I did not contact support properly and the issue remained unresolved. I would like to ask you to help me recover this old account. I believe it should be possible to detect the original device or phone on which I created the account, or the first mobile number linked to it, so that you can verify that I am the real owner. This was my main gaming account for many years and all my purchases and progress are there. I kindly request that you review my situation and help me regain access to my Free Fire account by verifying it through the first device or phone number used on the account, or any other data you can check.
