LG TV warrenty service unprofessional

I brought a smart TV from Kloppers. LG with two year warranty. The TV started having problems after a year (the online forums indicate it is a common problem of the remote not talking to the TV and an inability to connect online) It took around 6 weeks before a technician visited me from LG . What irks me is that LG gave me specific sates for the technician but he simply did notg come. This after I told them I would be taking a day off work to wait for said technician. This happened three times. When the technician did arrive he was unable to fix the problem so they took the TV away. Once at the depot i was told there was nothing wrong with the tv. A week later they brought it back but forgot to bring the *****s for the stand and the back/ Also, the HDMI ports at the back have been squashed and I can't insert any cables. I have phoned them more than six times and am still awaiting a solution. This is very unprofessional
