FNB Home Loan is Un-professioinal

When ever i got extra cash i used to deposit in my Home Loan account with the intention to reduce my repayment.FNB created a savings account within my Home loan (Bond) where they kept extra the money that i used to transfer.Who approved that account to be opened?For so many years the money sitting in that account without accumulating any interest.During the first lock down the made me to apply for Home loan covid relief which im paying back with interest.Why didn't the advise me that im having savings that can cover that Covid relief?Now that im aware that i have funds in that saving account which i didn't openor approve, im requesting them to return back the money as im having a Plan to use it.It is now Three week that i made an application and when i request an update they take forever to respond.The poor and bad service that im getting from FNB Home loan department.I went to my nearest FNB branches to try and resolve the matter but i was also told that they can help me as the Home loan department is not their department and they don't own any offices.

I only need my money back as it doesn't have any interest then i will put it for a better use.

for the past Three weeks the only thing that i got from FNB is excuses and till to date my money is not yet reflecting.Please help
