Poor rude Nedbank consultants

I am so disappointed of the collection department..this staff is so rude and they really need training for anger management because hai shame not making their ptp frustrate them and they end up fighting with us to cut the story short I’m having a vehicle finance with Nedbank and I’m owing 1month installment and they refuse to make an arrangement of making the installment of paying normal installment plus additional amount for 3months instead the last consult that spoke to me he tells me that they will come back to take the car and I rejected the contact..can I really get a call back to a person who is willing to make payment arrangements with me and can I get someone who is humble and sympathetic cos hai shame the once who are spoke to hai shame they are really heartless and they are just red flagging Nedbank shame their service is very poor they really need help it’s like they are taking their personal issue and bring it to us the client..they need a proper training on how to treat the customers cos I’m really disappointed right now and I don’t think even if the person is owing should be treated in this matter so if they are tired of working they should just quit the job since they are not willing to assist Nedbank customers with the smile on their face and they must not think of their debt when making arrangements..thank you..unhappy client
