Very Rude Customer Service

Very rude customer service agent at Woodstock branch. I went in to FNB to get assisted after telephonic assistance .I was told to go into to branch to have my issue resolved. I noticed an amount of R68.99 going off on my account every month on random days sometimes twice or three times.I reported issue ,tried to find out who it was ,filled in forms but still nothing. I went into branch the lady (Cheryl Pulse) was very rude ,she was even training someone at the time .She did not even seem willing to assist ,someone even brought her a cake while we we talking and that seemed more important than my issue. She asked me ridiculous questions like don't I know who I gave my card details too when asked her if she could find out who was debiting my account she told me how are we supposed to know .When filling in forms I was not sure how many transactions and when so I asked for bank statement she then told said to me don't you have internet banking. She was very rude and unwilling to assist. I have no problem with FNB but I think people who work in customer service should treat other people better .I would never be rude to her for doing her job but I will not be treated that way because I need assistance from her. Please do better Cheryl
