More than 5 visits to the Branch, still no assistance!!

I am so frustrated with Absa Bank, I have been trying to close my cheque account for the pas 3 weeks now. I have made more than 5 visits to their Branch at Durban-Musgrave centre. I have been speaking to the lady by the name of Lynette. my account is now overdrawn because of charges!!! the past 3 weeks trying to close one account!!! even more reason to never do business with Absa!! the service is absolutely pathetic!! apparently there is a hold there is on my account which they cannot remove according to their head office, so now I should have this account forever!!! this is absolutely absurd!!!
