Pathetic Service

I went to Spar to buy groceries and my bank card was declined three times and then i tried to do internet banking buying electricity and airtime as well as transfer money and all failed and then when i was trying to buy electricity there was a pop up demanding id and proof of address when they have all my details. Why they never phoned me if they don't want me to bank with them i can move my money to other banks , they treating me like i am there kid,and that's very very poor service. It is my money just unlock my card and internet banking and tell me nicely to move my money and close the account i don't have to be embarrassed like that.
