No Service from Standard Bank Insurance

I am out of the country and is trying to lodge a claim for a geyser that has burst on Sunday 10 March. The initial call to STD bank was answered, but as soon as it is transferred to the insurance department - it goes unanswered for up to an hour, when the call gets cut due to no response. I have tried calling early morning, midday and evening, SA office time, every day including today - i.e. 6 days now.. Still no answer! This international call cost most likely exceeded to cost for the geyser repairs. I have even tried going to Hollard Insurance as they seem to have partnered with you.. Their response time was phenomenal, but they could not help me as my insurance is directly with Standard Bank. I now understand why Standard Bank is rated the worse South African Bank in the Customer Satisfaction Index. Please inform me how to to lodge this claim as you have no email address and your calls to this department do not get answered!!
