ABSA client for over 50 years but unhappy!

Today somebody from Absa phoned me that speaks English with a heavy African accent! This guy try to tell me that Absa want to increase my limit on my credit card! But he must first ask me a few questions... So he ask me my idnumber, email adress, cell phone number etc... For security purpuses... That I understand... But then he ask me my home telephone number.... The more I tell him I dont have a home telephone the more he is ademant that I need to give it to him... I told him I cancelled my home telephone 5 years ago the he ask I must tell him what the number was.... Now I am 66 years old and cant even remember what happened last year how on earth must I remember what number I had 5 years ago? The result was I could not answer the home telephone number and he could not talk to me any further. NOW ABSA LET ME TELL YOU THIS..... Take my credit card account and push it in there where the sun does not shine!! I have being a customer of ABSA for over 50 years.... I dont need you or your credit card or your attitude!!! You make money from me so if you want my bussiness from me treat me with respect.... You are not my only bank! I have had it with you!!
