Standard bank home insurance

I lodged a complaint about stardard bank home insurance not answering calls. The customer complaints rest assured me that they will solve the issue as quickly as possible. It's been a week now still same old story. My geyser leaking, call centre not taking calls due to high caller volumes and customer complaints department still trying to solve the problem as earliest as they can. I'm sitting with a problem and I dont think it will be solved. Come month end they are quick to do a debit order. What is the next step I should take? These are the people who encouraged me to move from Ooba home insurance to them. Now I'm worse than being abused
