Dismal performance by Standard Bank

I have 2 claims open with Standard Bank - House 1 Burst geyser logged on 4 January - no response - Ref***0 House 2 long running water leak - dismal performance - fixed one leak - demanded excess and left with no repair to paving - still leaking so fast we have had to switch the water off for a month Ref***0 - nobody answers emails or the phone
