Bad Customer Service

Reported that the Hisense washing machine stopped working 2 weeks ago and nothing has been done ever since I received a call from Kevin from Hisense on Tuesday who insisted that we need to open the machine and try to unblock the machine. I told him I don't have the expertise to do that and would prefare for a technician to come through. Kevin promised that the job has been booked and a technician will come though. No feedback was received till I called Hisense today I asked to speak to Kevin and was placed on hold for 30 mins without the call being answered. I called for the second time and a lady called Veronica picked up the call and then when I discovered that Kevin didn't do what he had promised to do no job was booked. Veronica has to book the job takes a further 72 hours which I feel this is not how you treat customers. This is very poor customer service. Very unhappy client
