FNB Extremely Poor customer service

After 3 times to visit the Branch to sort a late estate, as every time they were looking for additional information, I could finally submit all the paperwork required by Late estate. This was after 2 years. Late estate dept contacted me on 3 April to confirm they have all te paperwork and it will take 31 working days t for the money to be paid into the bank account I supp****. That should have been the 18th of May. When I went to the branch again today, spoke to Simangele at Late estate whom alleges that they have system issues and payments are on back log. Today is 7 June, so they have system issues from 18 April to 7 June, no courtesy call from them or email as well as I requested a supervisor to contact me ... that was 14h00 it is 15:40 now ... no phone call. This whole experience reminded me why we moved our bank accounts from FNB years ago. Absolutely NO customer service!
