Poor service from Hisense

My 5 months old fridge stopped dispensing ICE, i then contacted Hisense to allocate a technician to come have a look. I got a reference number, and i got a call from the technician the following day to ask for my address. I then provided my address and the technician said he will call me back. 2 days passed without getting a call from the technician. When i phoned the call centre i was advised that the technician has booked the following day to come to my house to fix/ look at the issue. I then asked how so as i was never contacted to check if i was available on that day. They advised that they dont know, but they technician will be coming, but they will contact me an hour before they come to arrange that i be home. that day came and passed, i then send an email to them to check around 3pm as to what time as i have not received any call from the technician. i was told that they still on their way, but they never showed up. Its been a full week, and the technician did not show up. this is the kind of service we get from Hisense and its technicians. poor service
