Burst pipe, with no service from Standard bank after 8 days!

Returning from my Holiday on 4 January we walked into a water covered house and realized that a pipe burst inside the wall. I have tried logging a claim on 5 January but due to the claims department not working on a Saturday I could only log the claim the Monday. Hoping this will be sorted as a matter of urgency, to date no plumber has been appointed! Water is soaking into the cupboards, tiles being damaged and after 8 days and 10 calls to Standard bank, this still is not sorted out. Out of desperation I have contacted a other service provider to quote on fixing all the damages, I have sent through the request to Standard bank with no reply! In the mean while my utility bill is running up due to water loss and more damages are being caused.
