Login id n password is already created but i dont know what's my login id and password is not working

I m Mohd Ari Jamal . I m doing PGDBA from Symbiosis Centre for Distance Learning (SCDL), Pune. I have paid all the installments of my fees (1st installment of Rs15000 and 2nd installment of Rs10000). There is no due amount. My Registration no. of SCDL is 200921590

Unfortunately, I am unable to create my login id and password on www.scdl.net . i have tried alot to make my id on 24th&25th September '09 but there was some error messages whenever i tried to make user id and password. So i didn't get my user id and password. But when i tried to create user id on 13th November '09 there was a message that
"Your id is invalid". But i dont know what's my login id and password.
When i try to login on Existing Students they are  not accepting my id which i was trying. And if i submit my Security Question that's also not accepted. Please check out my problem.
28th November '09 is the last date of submitting  the assignments . If i wont get my user id n password i'll b unable to submit my assignments and also unable to give exams.

I have call the customer exacutive but no one is taking call and but i  have to always pay charges for that call.


Please solve my problem. You are the only hope for me. If you wont help me my carrier and money will spoil. I m mentally depressed just because of this problem. I dont have much time. Please do the need full as early as possible.

Thanking you,
