Bad service from standard bank credit card

Credit card division worst service ever paid our credit card.... every time we phone give it 3 days to clear then its blocked. We phone 2 unblock the card give it 5 days to unblock the card. Still card doesn't get unblocked when we ask why isn't it getting unblocked my husband gets told I don't know. Thats all he gets told I don't know they working at the bank why don't they know. My husband sends a email turnaround time 3 working days it sounds like they passing the buck onto another because no one knows what the heck is going on
