Hemalatha Ceriyahemu,

As there is no other option for you, so you need to talk to the concerned authorities of your college to provide you tc as soon as possible. You can write a letter or mail or any communication sources available to request for your tc. I'm sure they will certainly help you. In case they do not respond to you properly, you can go to even higher authorities of your college to complain regarding the same, however this case shouldn't come as they will help you for sure you just need to communicate with them.

All the best :)
