poor service

The morning we paid our account that was a bit late, up to date. We selected the option from our bank to clear money within an hour for extra charges of R40. We went to the till with our shopping and first asked to checked if account was updated. It was not. One lady went to phone and the other lady told us we can buy on the credit that is available. Then when she was finish we were told that the account is block. And the system only update every few days. They could not even say how many days. Not even an option to send proof of payment. Even today we got an sms saying we failed to pay our account and have to pay today! This is really poor service. And a waste of time and money. The staff did nothing to solve it were other companies like vodacom and edgars solve it immediately. I feel convince that they did not wanted to help us. There were even another customer who's card was not sort out for 5 weeks. We also asked that they stop the services on the card. Even that they did not do.
