MFC nedbank poor customer service

My mother has been trying to selling one of her car and MFC has been sending her back and Forth since Beginning of Dec 2022.They asked for 3 quotations from car dealers and she sent them and they told her it’s a process which we understood.On the 6/12/2022 Ngubane advised her to do the process via client service which she did.Mind you she sent her documents to mfc care and had to resend to assistance.Later in Dec someone called her about the new instalment for the shortfall and said they will email her the letter to send to the dealer.No email was sent.She called on the 3rd jan 2023 they said corneil(manager) will give her feedback and send her the email which never happened.She called again MFC and spoke to Maria who gave her ********** number which just ring with no answer.Today she called again No answer.This is unfair and unacceptable to still be chasing for answers on the sale of the car a month later .This process is dragging and come the 15th you will want your car instalment in full after she told you guys the reason why she is selling the car.Can someone give her feedback please!!!
