BitMart Account Sundog Crypto Balance Vanishes Without Transaction History Record

When I checked my BitMart account to make a transfer on July 31, my Sundog balance was visible, but when I checked again on August 3, it had completely disappeared. Currently, my account screen only displays a total asset value of approximately $13.51 USD; the Sundog balance is not listed anywhere, and if it had been transferred elsewhere, it should appear in the transaction history, yet there is no record there either.

I want to connect with live chat support, but I am unable to reach the support line, so I have received zero information regarding what happened. Being unable to learn the whereabouts of my funds, combined with the lack of a clear explanation from the platform, is causing me significant hardship and undermining my trust.

I demand that BitMart conduct a detailed investigation into my missing Sundog balance, provide a written and transparent explanation regarding what happened to my funds, and issue a full refund for the entire missing balance from my account.
