i have new information for my case but havent herd from the ssi office.

i have been denied already twice. im going on two years almost of trying to get approved. i now have my medical records and also recent mri results to help me with my case. i was sent a letter about 2 to 3 months ago stating to get prepared and what not becuase i was soon going to get a court date. thing is...i have yet to still hear from ssi office. im not sure what to do now, do i go in there and try to push things forward or do i just wait.. i hate to have to keep bothering them..but i am prepared for my case and need the help from disability because im unable to work so things are hard for me at the moment. what should i do?
