Bad service from ineffecient staff with no response or feedback regarding repairs

My fridge stopped working and a Samsung salesman recommended I use Liptronics. After several attempts to get the technician to my house, Jonathon came and repaired it. In less than a year it stopped due to the same fault. When I eventually managed to get him back he repaired it again. He blamed the lady making the bookings for the delays and confusion. He told me to contact him directly next time I needed his service. This time my fridge broke again in under 2 months with the same fault. I made another appointment directly with Jonathon who confirmed both 4 days before and on the day of the appointment that he would come to my house to repair it for the third time. I needed to make sure as I had to take the afternoon off work. But he failed to turn up. He did not call me to tell me that he was no longer coming. I tried 9 times during the afternoon to phone him and also messaged him via Whatsapp him but he did not answer either. I think he was refusing to answer when he saw my number. I could see that he read my Whatsapp messages. I do not know how Samsung keep Liptronics as their servicing agent. I recommend that you use another company if you can. If you are looking for inefficient staff who give bad service, fail to give feedback and do not respond to calls regarding a repair, then use Liptronics. Be warned.
