I disputed with Experian about XXXX, and the result had come back with the word : Remains. 
I then contacted XXXX XXXX on XXXX/XXXX/15, which they could n't verify any of the information on this account, then they said, they 'll contact the credit reporting company to update the information. 30 days later, nothing happen, I disputed it again with Experian, and the result is still Remains as of XXXX/XXXX/2015.
