Worst person to comunicate on the phone with

Claude from vehicle finance in Richardsbay phoned me now at 09:45 and was very rude because he is signing a client and wants me to fill in documents that he is supposed to do. When I told him that he is responsible for completing the documents he started yelling at me over the phone and was very very rude. He is the most unfriendly rude person I have ever met and he is not living the Absa values. He should go on a course on how to treat clients and people he interacts with.
