Poor service

I, Vimbainashe Natasha Ngwerume am appointed as Executor of a late Estate. I went to Nedbank Norwood on the of 6 October 2017 to open the late Estate Bank Account, I took the original Letter of appointment, original death certificate and other related original documents, I was told that the account will only be opened within 7 days . I went to Nedbank the deceased' life policy had to pay up her bond which was with Nedbank and there is extra money to be paid up into a Deceased Late account . I need urgently to distribute funds to the beneficiaries but can do nothing due to this bad service of Nedbank . No one has come back to explain why the account is not being opened .
