My husband has been with Fnb for more than 20 years

My husband has been with Fnb for more than 20 years. He has requested for hus investment funds to be transferred to his new bank... it has been 4 months already and yet no transfer has been done. All paper work has been signed and forwarded multiple times, we receive the notification that they are processing the request yet nothing is happening. This is so unprofessional and ansolute no service. If you phone to follow up you waiting time and money as there is absolutely no answer. Fnb we need answers or will you only assist once we have lost our vehicle and our home due to your lack of service
