Sent back and forth

On the of 25June 2020(***),we reported a geyser to Nedbank insurance. An electrician was sent and he said it's an issue that had to do with the plumbing side. Plumber came and sealed the leak. But said electrician should come back as the is something wrong with the electrical part. We have been sent from pillar to post when contacting Nedbank (spoke to Moses and Refilwe) since the 25th June the geyser is not working. And still waiting for someone to fix it. We are not happy at all with the service
