Loyal customer disappointed at customer feedback

In the past I have been very impressed with absa ***** in resolution for disputes on my ABSA buisness account.Currently I have around R55k on hold in my buisness account and no one can tell me why.

1.Spend hours on the phone with ***** service desk over the past few months going through all cases only to find them resolved in my favour. 2.Mailed every invetigator to confirm they have released holds,which they all confirm they did and confirmed they had no other open cases which they did. 3.Send a email to transactional ***** with every case resolved for conformation of resolution and no one seems to know why the funds are on hold.

This is not fair on me as a buisness and as all im looking for is a resolution to remove funds on hold in account but no one seems to know why the funds are on hold, with each department pushing it to the next with no feedback or resolution.

I don't see that it the customers duty to keep calling for feedback especially on a buisness account.
