SBSA LOAN2 and STANDARD BANK POWERCURVE are doing unauthorized credit enquiries on my profile.

To be honest i give it zero star

There are a number of unknown credit checks that have been recently done on my profile without my consent. MYy recent credit report shows that they were done by SBSA LOAN2 and STANDARD BANK POWERCURVE. I don't know why they are doing this because I do not bank with them and I have never app**** for any credit with them. This is damaging my credit score as it goes down each time they make these enquiries. Please stop it.
