Appalling service, poor communication / feedback

I am currently going through a bad experience with Hisense. I regret I had to resort to this sort of thing, and I hope I wont' have to go to other platforms. My main aim is to get my dishwasher (H13DESS) fixed, not to go on public spats.

Just 2 months ago I bought a Hisense dishwasher from Hi-Fi Corp Springfield, in less than just 10 uses it began tripping power. I immediately called Hisense (***3) to report the fault 09/01/2021. They said I should send an email (***) with proof of purchase etc. which I did later the same day.

On the 11th I got an email (Mpumelelo Prosper) asking for my address. On the 12th I got another mail confirming that a technician from Audio Master Visual would come and do in inspection (order ***), no specific date was given, but so far so good.

The gentleman indeed came on the 14th or 15th, he said there is in fact a fault with a "drain pump" and would return to install it once ready (no date specified). To my great surprise and dismay on the 18th I receive communication from Hisense saying the machine is fixed and the case is closed.

Immediately I wrote back saying that that was incorrect we still await a drain pump. Since then I have sent several other emails, and made phones and even drove to Master Audio Visual on Umgeni Rd Durban, where I was told they'd only come back when Hisense approves the claim. This is now the 30th and I have not received any response, no one picks up the telephone which drops by itself after telling you to hold for many minutes.

I hope to this is going to be resolved soon. I have been without a dishwasher for 3 weeks without any clear communication from Hisense.
