Sales Dept handling me like a ********

I wanted to upgrade my credit card and phoned the credit card division, after being given the run around I was to to phone their sales dept, which I did. I had the unhappy experience of talking to Harriet Kekane on 13 Nov at 12:58. She handled me like a ******** and a ********* because I could not remember to the exact sent every transaction on my account for how many days. Who on earth can remember such things - is that the only way they can validate me as a customer - by making me out to be a ********* and a ******** because I cannot remember certain things ? Meanwhile the airtime on my cellphone runs out trying to reason with this person. FNB if this is how you treat a loyal customer of 20 years now then I suggest that you contact me so that my accounts can be closed, and transferred to another bank.
