Can collection agencies report to Credit Bureaus at different times?

I had a account that was mistaken and put on my report when i was 15 years old it was for a past due cell phone bill which i never had. when i turned 19 i tried reasoning with the collections agency telling them hey this isn't mine you need to look into because im not paying this they tell me it is mine and that they wont take it off my report and lots of going back and forth so i say F it a couple years it will charge off and the sol will be up. HERES MY QUESTION if they reported to only 2 bureaus in 2003 and those were removed and now they know that they were removed can they make a new account and report to the third bureau and start a new sol from this point on for 7 years. keep in mind i have never taken responsibility for it and never said it was my account or my bill. they called me after the first sol was up and i told them everything and that its not my account blah blah blah and i haven't gotten a call since then so i fear now they might try to report it again
