I am absolutely disgusted with the service I received at Nedbank Musgrave

As the title states, I am absolutely disgusted with the service I received at Nedbank Musgrave. My aunts husband Kenneth Smith passed away on the 26 August 2022. Kenneth Smith had a funeral policy with NedBank, he also still had money in his account. Getting the payout for the funeral policy was a nightmare, the people working at this branch(Nedbank Musgrave) are extremely rude. They kept sending us away because according to them we filled in the form wrongly or we never had the proper documentation. My aunt is in her late 70s and she uses a wheelchair to get around, it's a mission getting to the Bank and when we get to Musgrave the Nedbank staff treat us with major disrespect. The staff also told us that we need a letter of authority from the master of the high court, so we went to town and waited the whole day for the letter, when we returned to Nedbank Musgrave, the rude customer care representive told us it takes a whole month to verify if the letter is real. This is a disgrace, shame on Nedbank Musgrave!
