No after sales service from Hisense

I bought a Hisense fridge/freezer in 2019. It stopped working, and is still under guarantee, so I logged a service request via the Hisense website on 01/08, and provided all the necessary information including the proof of purchase and my contact details. I received two emails asking for the same information again! Nobody contacted me to make arrangements to have a look at the appliance. On 05/08 (three days later), I called ***, and related this sorry tale. The agent contacted the local service centre, and someone arranged to come have a look at it. They never came, neither did they have the courtesy to contact me and let me know why. I call back this morning (06/08) and ask to speak to a manager. Karabo (agent) tells me that he will follow up with the service centre and ask his supervisor, ***nor to call me back. So the local service centre calls me to say that the technician couldn't come through yesterday due to a march blocking the road somewhere, and could only come out next Tuesday. Nobody works on a Saturday and nobody seems to understand, nor care about the great inconvenience experienced without a fridge! And two hours later, I haven't had a call from ***nor. Basically Hisense is showing me the middle finger instead of honouring the commitment that comes with the guarantee. So far I have encountered unparalleled incompetence, don't care attitude and pathetic after sales service. Nobody is bothered to try and address the problem. I would give them a negative star rating if I could. I will never buy another appliance made by Hisense. They happy to take your money and then ***** you if you need after sales service - absolutely disgusting! Oh and they also don't bother to read posts on their FB page.
