Uninterested in complaint

I used my credit card at a local supermarket and when handing the card to the teller who inserted it into the machine the purchase went through without me being asked to enter my PIN number.<br> This means that if somebody gets hold of my card they can purchase at will at that store.<br> I reported the matter to the store involved, and they said that they had received many reports of this happening with Standard Bank.<br> I then phoned the Standard Bank Customer Care Line and basically I was told that it can happen. They were not prepared to take it further.<br> I feel that their attitude towards me reporting what I see as a huge flaw in their bank's security was very concerning.<br>
