Two bonds open for one property and no feedback

I had an existing bond with FNB with my ex husband and i was in the process of doing a substitution of debtor which had been approved and i was approved a brand new bond in my name only, My ex app**** for a covid relief and FNB included the bond without consulting me, surely if you see there is a joint bond you need confirmation from both parties to grant the covid relief and secondly doesn't FNB check that the bond was going to be closed as the substitution of debtor was approved ???????

Now i have been granted my new bond for the same property that is only in my name, and fnb was meant to settle the old bond and instead now settled the NEW Bond , and still hasn't removed the old bond from my name. So i am sitting with two bonds open for the SAME property , i have spoken to 5 different call center agents who promise a call back and i never hear back. No one that i speak to can give me an answer , i even got a call from FNB to congratulate me for paying off my new bond when they were the ones that made the payment,

You have a call center full of people who cant give you answers and all they can say is im going to have to send this to my manager , do managers even exist ? because they dont even get back to you.

I am highly disappointed with FNB as i have only ever bank with them, if i knew that this would be such a mess i would of app**** for a bond at another bank
