Parivahan — Unable to give LL test

I have applied for LL test on parivahan.. I did the payment and everything. I got the message saying you can now give LL test and when I try to give LL test while logging in its shows invalid creditionals or invalid DOB format, although I have put right creditionals it's been more then a week.. I don't know what will I do now I can't go to the rto office that is the reason I applied for online LL test.. the don't even bother to reply to emails or pick up the calls..they don't even have refund options
PLEASE HELP!!!
