No response over Mortgage protection for Retrenchment

FNB has become the worst bank with the poor service we are getting as clients. I have submitted my retrenchment documents for my Mortgage protection exactly a month ago on the 14 April. And every time I do a follow up with my private banker Olga Dube she escalates the matter and after a week there would be no response from anyone and when I call the life claim department they tell me that the matter is being reviewed. All the other banks have long assisted me with my claims. My bank for over 15yrs is giving the poorest service. I'm the one who has to call them and find out about the update on my claim they are dead quit from their side and yet you even have your own banker but still no one can assist. This is ridiculous and unacceptable.
