Stupid service

I always pay my account using my ID number, I mean who forever carries their ID'S

I went to Mr price home mall of Africa to pay, to ****en PAY for heaven sake, not to purchase. I was told , I can't pay using my ID number, when I ALWAYS pay using ID NUMBER. THE BIGGEST MISTAKE I HAVE EVER MADE IN MY LIFE IS TO OPEN AN ACCOUNT WITH MR PRICE . The next ****** thing they will be calling me to pay, and boy I am waiting for that call
