Una Ndou - call centre agent

Hello,

I currently live in the UK and I called nedbank earlier this afternoon to enquire about my credit card and was put through to this lady, firstly the line was a bit bad, I told her and also adjusted my speaker and we could here each other clearly, she said security questions and she said she would send me an SMS on my phone to verify that I am the account holder, I asked why are my payments not reflected on my statement and she started said oh! this account this... and that with an attitude... I said to her what she is doing is read back to me the information that I already know and she's not helping, I told her that I have just wasted my money and energy making the call ???
