Mishandling of my profile

I lodge disputes many times regarding Prescription on my Capitec account and the same account has been on my profile longer that the required period but i was told that the creditor requested that the account stay on my profile only after i made many disputes and requesting for the evidence received from the creditor in order to take the matter to the NCR but they failed to supply me with any evidence and only send me communication that they have credible evidence but cant furnish me with the credible evidence. I am of the opinion that they Experian informed or connive with creditor to keep the prescribed account on my profile because on the eve of the account being removed the creditor send them communication.
