RUDE Call center CONSULTANT at ACKERMANS

I have a debit order in place with Ackermans for R500.00 every month. the past 2 months i had no issue and my account was debited at the instructed date. However i still get SMS's from Ackermans saying that i have not made payments and i will referred to Lawyers. I contact Ackermans on their whats app line on the 24th of June querying the sms and i was informed on the 25th of June that i have an active debit order active and to ignore the SMS. This month no debit order went through and like a responsible person i ask again on the whats app system and i was informed there is no debit order on the system after getting SMS's that they have increased my installment from R500 to R800. I ask why it has been canceled and instead of the whats app operator responding i get a consultant screaming in my ear that it is my responsibility to go and check with my bank why the debit order didn't go through. The arrogance of this consultant that called *** at 09:16 and her rudeness over the phone is completely unacceptable and i will report her conduct. Instead of acknowledging that it could be a system error and we can set up another debit order like i did before telephonically, she shouts that its my responsibility to go the bank and ask them why the debit order didnt go through. She was rude and disrespectful and needs to be reprimanded.
