Bad Service First National Bank

My fiance's mother passed away on the 23rd April 2020. Her will is kept by FNB and they are the executor of the will. We went online and reported her death on FNB online. Two weeks later we had a reply e-mail from FNB with a contact number. We called the number and the person we talked to advised that we should call Natasha Pillay at Estate Admin. We tried calling on both switchboard and her direct line and left messages and from the 12th of May to date had no reply whatsoever. This is the second incident we had with FNB, the first one was ********** transactions on my fiance's mothers account which was reported in December and posted on Hellopeter only then did we get a reply from FNB and acknowledged by FNB that they are dealing with it and will revert back to us, they never got back to us and now trying to get them to sort out her estate to no avail. Really bad service.
