Customer service towards the elderly is pathetic

On Friday, 11th September I was at the Westgate Mall branch in Mitchells Plain around 8h30. I was going to withdraw money from SASSA card but the ATM machine swallow my card. I waited until the bank open and l explained my situation to the lady that opened door. Her response was that I am not suppose to use my SASSA card at the ATM. Firstly she is chasing customers away, I could be a potential client and she is suppose to assist people at the help desk. To top it off she said my card was declined that is why the machine swallowed it. I didn't even put in my pin yet so how could it be declined. The SASSA card has Debit Mastercard symbol which means you can withdraw at any ATM with that symbol. I don't appreciate that she treated me like a stupid old lady. I might be old but I'm not stupid. She didn't attempt to ask for my details and that she would get back to me. Let say I am so glad that I don't do any banking with Standard Bank.
