Dg Shipping — deactivated indos number

Address:

F 25 Siddartha, 43, CP Ramaswamy Road, Alwarpet, Chennai, Tamil Nadu, 600018

Sir,
My name is sreenivasan. I hold a class 4 coc and my indos number is given in the certificate as 00el2429.
I have joined an institute as a lecturer and to my surprise find that my indos number is deactivated.
Sir, i have done all my courses from dg approved institutes.
Now, i have been unable to do any course and also my job is at stake.
This is a question of my reputation and integrity.
Please let me know the reason for the deactivation which is unwarranted and also please reactivate the above indos number as soon as possible.
Thanks
Regards
