Warranty- poor service

I bought a Hisense dishwasher on the 30/04/2019, after 1 year the dishwasher broke. Hisense has a 2 year warranty on dishwashers, I have send an email to *** to send out a technician. A technician came to my house on the 23/04/2020 and said that he will need to get a spare part which will take 2 day's if they need to get it from Johannesburg and 4 day's if they need to get the part from Cape Town. Today, the 09/06/2020 after 2 follow up emails and a call to their customer care line, I still have not received any feedback. I understand that the National Lock-down could have caused delays in business delivery however nothing prevents them from at least responding to my emails and calls with feedback. If the quality of Hisense products and service is this bad, I will never buy any Hisense products again. Job no: ***
