Credit record not updated

I paid up all my accounts on the 4th of December 2017 and sent paid up letters to TransUnion to update my credit record. I waited the 29 working days that they asked me to wait for the record to be updated, however, I received an e-mail after 20 working days saying that the credit record has been updated. I then asked the TransUnion to send me am updates credit report. The report was sent but no reflection of the paid up accounts was not updated. The accounts still show as outstanding. Very disappointing.
