Hi Sense Appliance poor service

Hi Sense Appliance In mid June I reported a faulty freezer door and water leakage. After sorting the water leakage telephonically they said they would phone me the following Monday to enquire how it is going with the leakage. Despite explaining the the freezer door was faulty, they totally ignored it. Monday came and went, no phone call. Phoned them again to remind them about the door. They finally sent a technician who informed me that the door was incorrectly installed. The technician came the Friday and said he would be back the Monday with the correct tools. A few Mondays have come and gone. Despite numerous messages and phone calls and promises that he will come that day, still no show. There has also been no follow-up from Hi Sense, knowing they should at least have had an account by now. This saga has being going on for two months.
