Hisense titanium 10kg washing machine

I wish I could give them a -0 rating because their service and their technicians are pathetic I bought a hisense machine 2 months ago but about 3 weeks ago something went wrong with the door it refused to lock so I contacted them on Tuesday 17th of june to let them know that there was a problem they told me they would take 3 days for a technician to come out and 21 days for them to fix the machine if it’s anything serious I waited for 3 days no technician cAme out then I contacted them again on Friday 21st of June they said it would take another 3 days for a technician to come out I waited until Wednesday the 26th of June and the guy cAme out he tried to fix it but he couldn’t my machine is left just like that but he had explained he will be back the next day as he has a door switch for the machine so he didn’t ***** in the *****s he left the washing machine as is until the next day cAme he told me his stilll trying to allocate the part he told me he will phone me back in the next hour he hadn’t called me back so I did and when I did he said me he is ordering the part it will come from Cape Town which would take 2 days so it would be here by Friday 28th june so when I contacted him again on Friday he telling me the part didn’t come but as soon as it does by Saturday latest he would be here I took his word for it I contacted hisense on Monday to ask them if they have recieved the part I gave them the reference number for the job and they told me there isn’t any door part available so I then went back to the technician and asked him he told me he has recieved the part but he will only make it to come on tuesday I phone him yesterday to ask him when he will be coming he told me on wednesday early morning so I said okay I then phoned him this morning he tells me he will be here in half and hours time but I’ve been waiting for almost 3 hours and he is refusing to answer my calls When I contacted hisense and asked them to either refund me my money back or fetch their broken machine and replace me with a new one which I have only used for a month of having it because it broke in the next month they tell me they can only replace me if they cannot fix the machine but it has been 3 weeks of me not having a machine how much more longer and patience can I have? I would never recommend anyone purchasing from this brand again stick to defy Samsung or LG they will never let you down
