IGNOU BCA to whom should contact for what latest updated details for students

Not yet updated your lab marks for exams like BCSL-013 or BCSL-022, even after declaring result for other students? first question is Whom should I contact?
IGNOU Assignments marks still not updated ? Who should I contact?
Books not dispatched or material returned what to do ?
Study center and RC are the immediate answers. But most of time it won’t work for some issues.
In my case my BCSL-013 lab1 marks still not updated, even next sem exams going to start soon. I am clueless as I am not getting any hints from anywhere. Then following contact list helped to sort out issue.
I sent mail and got reply that marks are updating in next update of result. Tension free now.
