Delayed response and a rude technician from their Hisense supplier

We bought Hisense fridge from game in September 2018, 4 weeks ago we started experiencing issues with the fridge as it started defrosting thus resulting in food being spoilt. We reported the issue on the 18th of March, and kept on following up until the 8th of April when Hisense sent their technician to check the fridge. 2 guys came and they found me (a woman) alone, the guy was soo rude and dismissive. He left without doing anything because every fridge defrost 4 times in a day. when I told him that now the food is spoilt because of this issue he dismissed me and started calling me names. I am really not pleased with service I received as my fridge is still not functioning well.
