Warranty Repair Service Appalling

I logged a repair for a dishwasher repair under warranty on 2 June it is now 23 June and my dishwasher is still broken. I’ve struggled to get feedback and to even get technicians out to my premises. The technicians only came on the 15th of June almost two weeks after requesting it and advised they need to replace the aqua hose but it needed to be ordered. 8 days later and I literally have received no feedback as to whether the part is even ordered let alone when we can expect a working dishwasher. The service is appalling considering I chose to support hisense over defy and LG which were my alternative choices in product. job number ***
