Stranded and no way of drawing cash from SB

Let's understand something very clearly. I will NOT tolerate these persistent problems that I have been experiencing ever since my Debit Master Card was issued. This is the NOT the first time that I have been stranded without cash because of a DAILY LIMIT that always seems to be reset to ZERO. Anyway, today was the last time this ever happens. Do we understand each other? What is your problem? What is the problem with your awful Card Management System? Why is the limit constantly being set to NIL??? Today was the last time! Understand? Fix it or let's close the account. Got it?????
