Can't get support from Microsoft Store

I am trying to register new developer account on MS store, but review last more then 2 weeks. They asked me for additional documents and I uploaded it, but still no response. I tried to go to Get Support link, but I got this error:

{

"code": "EHCT4001",

"message": "EHCT4001 Sfb does not exist or user context does not have permissions to it",

"operationId": "608351b0c144db408f7baa799b5c787d"

}
