Non existent service

I logged a claim on 23/7/21 for a damaged geyser. Standard bank sent Bathopele Construction, one of the worst plumbing services that ever existed! they installed the geyser and completely messed up the plumbing that we have not had hot water ever since. I've been on multiple calls with stupid Standard bank agents working from home and they keep going in circles sending surveyors and electricians even after it's been established that the pipework done by their original contractors! On my numerous calls I asked to speak to managers and supervisors at standard bank but it seems like they're too busy to entertain calls from the very same customers that keep them employed! My SIL case ID is 21/059982 - lets see if I even get a call back, otherwise I'll have to drive through their buildings like other irate clients to get their attention!
