Horrible service and feedback on a simple card delivery

I have been struggling to get my cheque card delivered to me. 7 wrong or incorrect instructions from Standard bank in a month and charged twice for a home delivery never requested and they used my previous address for home deliveries. When I asked them who issues or changed my delivery instructions they tell me thy do not know. How can a bank not know? is the security up to date. regular 30 to 40 minute phonecalls, visits to bank and everytime just sorry and more empty promises.
