NEDBANK - POOR SERVICE

I CALLED TO QUERY A TRANSACTION - I TOLD THE PERSON ON THE PHONE I WOULD INVESTIGATE THE TRANSACTION, AND THAT HE MUST NOT BLOCK MY CARD. TODAY I STOPPED TO PUT IN PETROL! MY CARD HAS BEEN BLOCKED. I HAD TO LEAVE MY SPARE WHEEL AT THE PETROL STATION AS I COULD NOT PAY FOR THE PETROL. I CALLED THIS MORNING, ONLY TO BE TOLD I NEED TO VISIT A BRANCH! NOW I NEED TO TAKE TIME OFF WORK! MY PETROL! THIS IS ABSOLUTE ******* SERVICE!
