BigRock India — shared hosting database not access using sql server

Address:

Vadodara, Gujarat, 390012

I was purchased shared windows hosting from a big rock.when I try to access my database but unable to access my DB in SQL server. For Database purpose we need to use MS SQL Server so when I tried to connect with it first 20-30 minutes no databases display then after it displays blank.
I already talk in live chat as well as generate ticket but those guys always come with irrelative solutions which are not related to my problem also they are not cleary to say that we can not solve your issue.
