Dg Shipping — indos number deactivated no 00el2429

Sir,
My name is sreenivasan with indos number 00el2429 which is deactivated for some reason. I have done all my training from dg shipping approved institutes.
I have been trying to contact through phone or by email but there is no response at all.
Now i have got a job in a training institute but unable to do courses since my indos number is deactivated.
Kindly activate the same so i may do the said courses asap.
Thanks
Sreenivasan
