Refuses to assist because of one question, after answering 8 other questions

I have a credit card with Standard Bank which i want to close. Went to the branch 9 MOTORCITY CAPITAL PARK, VOORTREKKER RD, LES MARAIS. Woman at customer service told me i need to speak to the credit card division who takes me to a table, dials the number and leave. No body else at the table. I listen to the options, before i could speak to someone, i am at the survey. Easy for a customer service person to not speak to clients and put the phone down. I do the survey and said no to all the questions. I redial the number, still nobody at the table. Speak to someone, as usual, you cannot catch the name. This was at 10 am on 17 June, call is recorded. I answer about 10 questions and the woman asks me what is the limit that i got when opening the account, this was about 8 years ago. I could not answer this, although i answered all her questions to identify me. Then she refuses to assist me because of this question. Says to me i need to get one of the consultants on the phone. I told her that there is nobody close to me from the bank. She refuses to assist me and carries on that she needs the info. No wonder people are closing their accounts. I am done with Standard Bank. Very disappointed with the service i received, but that is the way you treat your customers. You can learn from Capitec!!!!!!!!!!!!!!!!!!!!
