Calling or texting client prior to stopping a card

I recently did a PayPal transaction and got my card blocked without being called or warned!<br> This is BS! The bank greatly inconvenienced me by stopping my credit card without warning, when I called the call centre, they claimed that they \normally do""; to block my card UNLESS you have got hold of me or a client. What Standard Bank initially did was send a message to call the credit card division asap; but it seems only after the card had already been blocked. <br> I have a R70 000;00 facility overdraft on that card;I know they are \""in all good intentions\"" trying to protect \""their money\"""
