Bad Service

I am very disappointed with the telephone service i received from the collection agent of standard bank. I received the call from Standard bank regarding my credit card that was not up to date, The agent was very rude on the phone keep on repeating that i am Memu instead of MR. she kept saying that up to three times even after correcting her for 3rd time, The agent name is Mpho and she called with private number at 13h40 03/10/2015. I would like to request the telephone conversation with her as this is a descremination and I will take this feather.
