TU cant find spilt file? common?

After finally reaching a human at TU. their automatied system requires entering credit report number but golly gee, they dont issue you on with online reports. I had to punch a bunch of numbers in the keypad to tick the automated system off enough to get me to a human. low and behold I got a human. I said I had thought i had a split file. he entered my info and all he kept comming up with was what I was getting. 95% of everything else is gone. it can stay gone for all i care, but doubt it will. the rep kept saying all he could find was a couple collections that i saw when i pulled it. he said he could find nothing else. is it safe to assume that he simply didnt look very hard or can a split file actually hide from an internal request as well and give the rep the impression there is nothing else? OR when there is a split file the TU rep should be able to see it no problem?
In any event he did delete the former address that was on there that ties into the two collections that remain. Will that address deletion improve odds of those two collections being unverifiable?
More importantly worried about this probable split file. Is it feesible for data to get lost within their system and never reappear? the rep was trying to tell me that perhaps the other creditors were simply not reporting to TU in particular. What? all 20 of them??\\anyone have a similar occurance with them?

 

I also went to WK, and same dice there. all they pulled was the 2 collections and crappy score because nothing else existed on the file except two derog collections.
