Horrible customer care

On 26th June, I contacted Hisense regarding issues with the dishwasher purchased in January. A contractor visited on 27th June and identified a factory fault, recommending replacement. Around 3rd July, upon follow-up, we were advised to contact Game store for urgency on the job number due to our refusal of repair or wait another week. On 11th July, we inquired again about the delay under warranty, being instructed to contact Game. My husband declined, stating it wasn't our responsibility. Subsequent attempts to follow up were met with disconnections or prolonged holds after providing our reference number.
