Pooooooor after sales service

Poooooooooooor service!!! I ordered a dishwasher from HiFi Corp on 28 Sept 2019 and it lasted 3 weeks before it broke!

Can't get a hold of anyone there, the email line tells you to call a store and book a technician, but no one ever answers the phone!!! Absolutely disgusted with this level of customer service because they really don't care after they have your money.

Customer number: *** Invoice number: *** Order number:*** Dishwasher make and model: Hisense 12plc SS Dishwasher H12DESS1

Someone please assist!!!!
