Extremely bad service from Hirsch's and Samsung

I bought a Samsung washing machine which is faulty (still under warranty) since 12 September and we have been juggling between Samsung and Hirsch's to get this sorted out since then. It has been 3 weeks now, and I have spent hours on phonecalls and communication to try and resolve this. T long last I was told the machine will be exchanged but nothing is happening. I cannot get a straight answer out of Samsung or Hirsch's.
