BAD CUSTOMER SERVICE

I just called ABSA to enquire about an overdraft and how to qualify, The lady that I spoke to (didn't get her name - unfortunately) didn't seem very interested in assisting me as she said that this is going to take 10-15minutes. so I asked her if she was willing to assist, it seemed that she was shocked that I asked that question, I mean I called ABSA so clearly I have time to speak, she rudely hung-up on me!!! now to call again and wait until and if another consultant will assist me... Real bad customer service - NOT COOL AT ALL
