Disgusting Customer Service

I recently got approved for vehicle finance through MFC after which I received a call offering me a cheque account, the account is to be credited with an amount of R200 for the duration of the vehicle instalment which is 72 months provided that the MFC debit order goes off this account and that I access and use the banking app

So I went through the process of opening the account and switching salaries etc...the debit order has since gone off and no amount of R200 has been credited to my account

I sent emails to Nirhen Sriram (sales consultant) advising of this, he rep**** to my emails advising that the bank charges would be reversed and he would call me back to advise how the R200 credit works ......I'm not sure what is there to be explained as he said the credit gets credited into my account once the requirements for the month are met

He is not as quick to call me every 5 minutes like he did when he wanted me to take the account up, I want this resolved , I want these bank charges reversed as an overdrawn account reflects negatively on my credit profile ......the charges need to be reversed alternatively I will be forced to close this account as the credit was the only reason I opened this account

The service is pathetic and disgusting!!!!!!!!!!
