Unauthorised transaction by FNB

I have a home loan with FNB bank which is supposed to end August 2025. When I took the bond the bank sign me up with third party which is Outsurence. At some point I went to branch because I wanted to change the insurance but I was told of long procedures, as a result I remained with Outsurece. This year I paid a bigger amount so that I can finish the bond early. Then I called the call centre to enquire about the balance, August my balance was around R7000. The person who was assisting me told me that since I am about to finish my bond someone will call me to discuss the insurance. Later in August I received a miss call then followed it up, only to find that it is the guy who said he was from Outsurence he wanted to know weather I am continuing with the insurance. I did not want to commit myself with someone I did so I said I not no he must call me On Monday, which he never did. As I was not expecting to be called by a third party I didn’t make any follow up and waited for the bank to give me a way forward.Yesterday I decided to check my balance on the App with the intention to divide it into two instalments. To my surprise my balance was R15.517 then I checked my statement, only to find that they Outsourced R9526.41 which is covering a year fee. I lodged a complaint with FNB yesterday. Today I was called by a rude woman she demanded the dates I have talked to their call centre agent, the guy from Outsurance and all other call. She said when I was signing up for the Home loan it was part of my agreement that is how it’s going to be. She said I must go to Outsurence and make a cancellation myself.

I feel that FNB has violated my rights as a client and that they are steeling my money.

Please I need your assistance in this matter.
