Refusal to submit accurate account information to Experian and Transunion

They are refusing to update my ITC profile to show that the account is active. I pay the account monthly but on Experian it's reflecting as a closed account. They are saying they will send me a letter of good standing, I don't want a letter of good standing I want my account to be corrected to reflect the correct status and payment history at Experian and Transunion. They are saying the don't have a control over what experian updates but experian receive instruction from them. The account numbers are not corresponding, the opening and current balance are not corresponding with information at Experian but no one is willing to fix and submit the correct infomartion at Credit Gateway even the Manager's cause yesterday I spoke to the manager who said an operations manager will call me. I don't want call I want then to submit the correct information to both experian and Transunion and send me a confirmation in writing that it's done.
