Extremely poor customer service

On the 27 November 2015 I made a call to Standard Bank Home Loan Legal Collections to make payment arrangements on our home loan account. Duwayne was the officer who RUDELY answered the call and offered nothing but POOR CUSTOMER SERVICE with no sign or willingness to listen to my arrangements or problems. The guy was nothing but ARROGANT, UNPROFFESSIONAL, DICTATORIAL AND FULL OF THREATS, which gave me the impression that he was enjoying other people's problems and not willing to listen or offer any kind of assistance whatsoever. This even after I tried to warn him not to intimidate or threaten me about handing over our account to the external collectors. Furthermore, to my surprise he continued with his stinking bad customer service by telling me that \HE DOESN'T CARE HOW I FEEL"all he want was for me to pay my account failing which he will continue with the external collection"
