Hirchs poor customer service

I went to the Centurion branch on Friday 8 March reporting that my LG fridge thats still under warranty is giving me problems. Mark the branch manager opened a job card. Later that day someone from LG called me to make an appointment, I called the person back he said he will call me but didnt. Tried calling the person but not taking my calls. Again I had to call Mark that this is not sorted, no one called me to follow up if this is sorted. Hirchs providing the service to me but cant follow up with me. Again on Tuesday someone called to make an apointment for Wednesday. My wife was waiting for the technician but didnt come I also tried to call him. Again I had to call Mark.... Not LG or Hirchs is accountable or credible to honor the waranty. I gave them enough time to resolve. I will take the fridge back on Saturday and I will get my money back. I am gatvol for the poor service. I am not going to negotiate! Should Hirchs not follow up with me the customer checking if this is sorted. Mark said he will call me today but didn't...
