NO WATER thanks to LiveStainable

I ordered a borehole pump after installing pump didn't produce any water. The Plumber pulled it out to check if they had do something wrong but found nothing wrong with the installation so I had to pay for a second day. Testing the pump in 210L drum with clean water we could block the end of the pipe by hand with little to no pressure. I eventually got a reply from LiveStainable they said because it had been installed they can't refund me and the unit must go back to supplier. Now where am I going to find a waterfall 80 meters high so that I can test the pump before installing it??? I have now had to buy a replacement pump as we can't wait for Livestainable to do something when we don't have water, it costs us two thousand rand every four days to get water delivered.
