unable to buy eletricity using Internet banking

Over three months ago I closed my bank account with standard bank to join capitec. My biggest mistake ever. I was told I will get internet banking and it's faster and user friendly. I then tried to load my meter number as a beneficiary but couldn't as it gave me error messages. I called them and was adviced it will be fixed within few days. After a week I emailed the agent who was assisting me and was told it's fixed but nothing. She then said she will ask their technical department to assist evem today am still waiting for their response. Really this what we get for this cheap staff
