Hello sir,

As you are aware of the fact that counselling process is done to secure you a seat and choice of the branch is made on the same day. 

I understand your concern as you even have a good rank in SRMJEE. But just contacting the college over phone call or mailing them to their help desk won't do you much good. I would instead recommend you to visit the main campus as soon as you can and have a chat with the authorities stating them your situation.

But keep in mind, you would have negligible chance of getting into their main campus (the best), but you have pretty high chances in getting branch like NCR.

Hope it cleared your query!!
