Makro warranty and The use of unprofessional Master Audio Visual to do repairs

Your warranty in using Master Audio Visual to do your repairs does not bode well for the makro brand. These guys are very unprofessional and have wasted 2 days of my work leave waiting for them at home, when they said that they are going to deliver my washing machine and have not done so. I tried calling them to no avail. I have been without a machine for 3 days now and no loan unit available. I don't know when they would have my machine repaired as there is no communication from them whatsoever.
