Misleading information

I got a call from one of Nedbank agency in May asking me to move my vehicle installment into my Nedbank account so receive R200 cashback everymonth asked which account type they need for me to qualify the person advised as long as it is a Nedbank account I qualify,so I moved my debit order into my Nedbank account the June installment went off from the Nedbank account but I didn't receive cashback then I decided to call the call center spoke to someone advised I will get it by Friday which was the 05-07-2024 but I didn't receive it,tried calling again but everyone who was taking my call to assist from Nedbank kept on cutting the call as soon as they hear what I am calling in connection with....One guy finally answered and advised it is started that I don't qualify for the rebate asked why he advised because of my account asked him to ask the manager to listen to the 1st call which was done by Nedbank asking me to move my debit order and get back to me as I feel like they gave me incorrect information to move my debit order which is not treating the customer fairly as I need to do transfers for MCF to receive their installment on time at Nedbank....I feel like I derseve the rebate on my car installment as Nedbank agent called me and advised me I qualify for it even after asking which account is needed for a client to qualify
