Please help

Hi team, Since a month I got this error. I repeatedly contact seller support, but still, no luck. There is no such known account listed in this GSTN from us. As an business owner I can confirm this. Please guide us to resolve this at earliest. If there's any account listed in this GSTN, please remove. As surely I can state this account must be inactive. As I never got such GST file from any of this suspicious account.
