Hi,

Well once something is submitted online and an option of change is not given then no change can be made further. You can only work ahead by contacting the officials. Try reaching them on the other numbers other than the toll free number and also email them about the same as well. I hope that way you will be able to solve this issue. Let me know if none of that work out. I will look for other option.

I hope my answer helps.

All the best.
