No feedback received after nearly 2 weeks

We went to Nedbank Wonderpark 4 times with documents to change the signatories on our NPO account.VLU Jakaranda Streek. When the branch staff were happy at last with the documentation...We gave the documents to Petrus on 19 May. He said he will forward it for approval it could take 48hours. I also gave him my cell nr to call me when the docs are approved. Keeping in mind...that you cannot call this branch, i had to drive there again after a week passed to find out why I heard nothing from them. I was told that the reason is because they did not getvan answer back yet...i must wait for the call. But now it is nearly 2 weeks later...still nothing from Petrus or anybody at Nedbank Wonderpark. May we please get some feedback! You are waisting my petrol and time to keep on driving to the branch.
