Unable to use available overdraft

I made 3 phonecalls to the call centre to confirm that once I had paid up my overdraft balance I would be able to use the overdraft facility once again if needed. Despite all 3 agents confirming this would be possible, and the paeony halong been cleared earlier this week, the card is still declined when I attempt to make purchases. Standard Bank seem to have **** and I want my overdraft to be available as promised!
