Geyser not heating

Hi

I logged a call with the after hours 24 hour service regarding my geyser not heating at 7h00 on 6 September 2020. The plumber came out and checked the geyser, then stating that it’s the element that is fine but I need to call standard bank again and get an electrician out as it is the switch on the geyser that is not working. The plumber has checked the geyser for over half an hour. Instead of checking the element they tell me to change the drip tray, this was not the issue. So I have called standard bank and logged a call for an electrician, they came out, changed the switch, and said it should work, after 2 hours they called back to check if it’s working but it was not heating. So they said I need to get the plumbers back as it is the element. I called standard bank again. Spoke to Gugu who also helped me in the morning. Gugu has tried calling the plumber again but they don’t take the call. It is now 16h00 and still no help. I asked if they can assign another plumber, but Gugu said no as a call is already logged, and the plumber from the morning need to fix it. Firstly they diagnosed the problem wrong and now they still don’t answer to fix it. Gugu said maybe they have closed the business at 16h00 therefore they don’t take the call. If they are closed then why is there no other plumber assigned? Surely they should work 24 hours if standard bank is 24 hour service. Gugu said they cannot help me now as one call is already logged so I need to wait until this plumbers take the call, or I must call back in the morning for another call to be logged for new plumbers to come out. I think this is ridiculous as it is a 24 hour service and surely another plumber can be assigned. We now have to wait until the next day for the geyser to be fixed. Terrible service from standard bank.
