Siemens Washing Machine Drama - No luck with the Call Centre

We spent around R25,000 for a new Siemens IQ700 washing machine from Hirsch's and in the beginning, was really happy with the purchase. As we have a stacking installation, we had arranged this with Siemens South Africa directly and the job was completed. About two weeks ago (and this is us having the machine for less than a month), the water alarm started sounding and I could hear it was struggling to get water into the machine. I phoned Siemens who sent out their Technician for fault finding. I was told that we should replace the water outlet from the wall as it was rusted. I took the advice and had this replaced by Burgess - the cost, R1900. We re-attached the water pipe but still the same problem. I then tested another Siemens pipe which we had, and no issues - this was attached to the new water outlet from the wall, water flowed freely. The new pipe with the machine, no flow. I have now struggled for the past week to get the Technician back here to re-install the pipe (despite having several promises of this happening) - calls to the call centre who had to get hold of the Technician - to no avail. We're unable to move the two machines as we were warned that we must not pull on the machines - even Burgess staff said that they are not willing to re-install the new pipe. R25,000 for a machine and I can't use it! How many calls must I log with empty promises? Surely there are better machines out there in the world where you get actual support.
