Appalling lack of customer service placing customers at risk

Appalled by the complete lack of customer service or accountability from Standard Bank Insurance. It is not possible to reach anyone by phone, have been on hold more than 30 min on three occasions, no response to multiple e-mails (despite reviving automated response telling me someone would call back in 2 hours), 2 broken promises to send an assessor. This has left my home on a dangerous state for nearly 10 days with no progress. How do I actually access this company to get the service my premiums pay for ? Extremely disppointed and very frustrated
