Sai, GITAM GAT has been already conducted in 3 phases the last one being conducted from May 20th to May 23rd as a Proctored Online Test. Now the applications are still applicable but the next phase of online or offline dates haven't been officially released yet. So that is the reason why though you have applied, you did not see any date per se for the exam. The last date to apply for GAT has been extended. May be you will have to wait to hear from the officials through your Registered Email or Mobile no# regarding the date of the exam.
