Loan account I know nothing about

Good day

I am Thabile Notshe I have an issue with sanlam as I went to Capitec Bank to apply for a personal loan to my surprise I was declined because of arrears that I have at sanlam personal loans and that came as shock to me as I know nothing of some sort... I tried calling sanlam personal loans bt no one could assist as they say they have nothing on I'd number I then called sanlam client even there I could not be assisted for the same reason, they then put me through direct axis even there same story now I'm frustrated coz no one can give me a straight answer regarding this account under my name and this is making my life hell as it is blocking me from making future applications
