Account paid up but not closed or removed on Profile

I have 3 accounts from the same company that show open- all these accounts have been paid up for over 60 days- months even, i tried disputing them and added the paid up letters but my dispute gets closed citing not relevant. All i want is experian to update my records, these are paid up i even have paid up letters but when i go to www.up.experian.co.za. and select dispute i cant attach when i select option of account - it gets removed i cant query the said account, when i choose duplicate it gets closed that its not a duplicate. This is wrong because my score keeps going down for an account i paid up a long time ago that experian is refusing to assist with- the call center number never goes through, i logged a dispute with transunion and it was resolved in less than 10 days,experian keeps closing my queries , this is pathetic
