Inconsiderate service

I went to Standerdbank Centurion this morning(07/03/15) to change my surname because I got married. The assisting consultant said that I have to wait 7 working days for a new card. I asked the consultant if I can still use the current card and her response was YES I can. When I tried to draw funds this afternoon the bank teller swallowed my card. I phoned Standerdbank head office, the person cancelled my card and said that they should have given my a debit card untill I can get the new card. Now I have to wait 9 days without any cash or card available to me, how should I buy any necessities for almost 2 weeks with out a card or cash. I am strongly considering to change to another bank due to this extremely bad incompetency.
