Disappointed and angry

I have viewed two different credit sources Pulse and Kodough and both reflect my NedBank credit card is in arrears. After querying this as I knew it to be wrong I contacted Nedbank which they confirmed is incorrect information provided from the credit berreu. My account is indeed up to date and active and most def not in arreas. I was advised to sort this out with the credit berreu. Very disappointed because now I should run around and dispute this information. When it's my bank that provides the information to the credit berreu. My score has dropped and it looks like I'm a slow payer but I credit card is paid every month. Who needs to fix this mess?
