NAME AVAILABILITY - RUN SERVICES

I had applied for Name reservation by paying challan of rs.1000, but my name has been rejected due to some trade mark issue. and my challan has been remarked for resubmission. later I applied for new name by using that service with same challan but at the time of submission I got a message internal failure and when I tried it again mca portal is saying that my challan is not under resubmission category. I also raised query on mca website , they mailed me it is solved but it is still showing same message. Can anybody guide me on it. I have alreday lost 2000 rs on Run services.
