Incorrect data negatively dropping my credit score

I have just received my latest Credit Score report only to find that my score has dropped 18 points thanks to a new credit product under my profile from Absa. The only product I have with Absa is my car insurance and the premiums are up to date. The new product opening date is the 1st of June 2025, which happens to coincide with the annual renewal date for my car insurance. Balance outstanding on said product is R2 148. I need the correct data to be submitted to Experian to correct my records.
