utter rudeness

called the call centre today around 02.00pm. a consultant by the name of Palesa Hlakotsa was assisting me . she put me on hold for over 15 mins as per her i dont understand the deductions on my account. she came back and wants me to understand what she was saying. when i asked her more questions , she then removed the mouth piece overheard her telling a colleague " bathong habatli homamela" the colleague then said something . when i said to her that i was listening to the conversation, she then said she was explaining to a colleague. i requested the name of the colleague she refused and said she doesnt know her as it is a 'large' call centre. im demanding that you pull out this recording. she is blatantly very rude . im having a problem on my account for an amount thats missing deposited today
