Bad Service

I sent my blender on the 16th January 2016 at Hirsch to be fixed as it is still under guarantee. Two weeks later I went back to follow up and I was told the blender is still with them but they will call me with the progress. Its now 12th February and I contacted them and I was told that they had not worked on in as yet. Its almost a month and no one seems to bother. Its just ridiculous no one seems to know what's happening and I'm only receiving excuses.
