Pathetic service from FNB staff

FNB staff (Reneilwe Matape, Rodney Ngubeni etc.) have no regard for client service what so ever. I have been calling almost every day from the 05th of January up until today 17of January 2024, I still have not been assisted instead every agent tells me they will follow up and get back to me which they never do. They could not careless about assisting a client in times of need. I requested a letter from FNB which I needed to submit to my vehicle finance bank so that they can reimburse me for some costs incurred due to a double debit in December. The vehicle finance bank was willing to reimburse me on condition that I submit the said letter from FNB. It has taken FNB more than two weeks to draft the letter which I still have not received. The service is pathetic, some agents are not equipped for this kind of job and require further training.
