Disappointed in Standard Bank Insurance

Logged a claim with standard bank insurance on Saturday 11 May 2019 advising we have been without hot water since Friday 10 May 2019 as the geyser is faulty baring in mind we had the geyser replaced in February 2019. Plumbers came to check and advised that the manufacturer needs to see to it as it's still under warrantee.. no feedback provided unless I call in and wait 20 to 30 minutes on the line.. it's now Monday evening and still no service. I am highly disappointed in this level of service as I pay my insurance every single month I am considering to switch my home loan as well as my insurance if this is the service we getting. my claim number is 19/039523. I just hung up the phone now after holding for 35 minutes.
