Dishwasher not fixed

My hisense dishwasher stopped draining water and started tripping plugs, I reported to Hisense on the 7th of December and a technician only came on the 28th to replace the parts but it still tripped plugs. He said he will order another part and till today I haven’t heard anything from them, when I called Hisense they tell me that the job card is closed because it shows that the dishwasher was fixed. The technicians are subcontractors to hisense and Hisense didn’t even bother to call me and find out if everything is fixed to my satisfaction.
