Account Frozen for 2yrs

Just wanna lay a complaint about fnb I used my account at Athlone then after that I was told a ***** was suspected on my account but the money went through on the purchase. Since 2018 my card has been on hold or frozen. I went to different branches all saying its out of their hands, I wasted petrol money, my time, my energy with no help, they put me on hold for so many times after saying I must talk to the investigator then boom they put the phone in my ear, at the branch they telling me stories that there's nothing they can do, they even **** (Branch Managers)saying they gonna call me i must leave then I leave I wait for the call But nothing. I went to Lansdown (Closed) Vangate Woodstock Zeenveenwavht Tygervalley Gugulethu All out of their hands At Tygervalley they even told my gal friend to pay R313 so that they can reverse the money deposited and they rejected the application saying it's unauthorized person who reversed the money, that account is linked with my gal friend, she transferred 1060.00 by mistake on that account, they refused to give it back saying the account was on minus so if it's on minus they can't reverse it they can only reverse the full amount that was deposited Last month again R4010.00 deposited by mistake on that account they still refusing to reverse it, the account has been investigated since 2018",its on hold but its keeping the money, now it was 4521 balance but now it's becoming less, so I would really like fnb to give back the money as they can see where is the money coming from, they can close the account because I am not getting any help from them all the response I get is the bad attitude and that we will call u, this is my money, I am not asking the bank money here Thank you
