Call centre not responding

Since my father passed away end of August I have been trying over the last 2 months to close his bank account and credit card with Nedbank in Herm****. I have been forced to use their in-house telephone to do this as they apparently cannot do it in the branch. I have tried twice via this call centre phone. The first time I held on for 20 minutes with NO response from the call centre! I tried again 2 days ago and held on for 11 minutes with the same NO response! This is ridiculous! I do not have the time to sit there and wait and wait. All thanks to Charlie for doing his best to help me but he also gave up. Fees are adding up on these accounts and I am not going to take responsibility for it. I will now just let the account hang there until they decide to close the account. I will now also close my own Just invest account there. Thank you. A. Hugo Gotze ( son of the deceased A.R. Gotze)
