15 days without a fridge

My Hisense fridge stopped working on 1 June. As it is still under warranty I contacted the call centre at Hisense. None of the numbers work so the only way is via email. It took 2 days for a technician to arrive to check it out. It couldn't be fixed so it took another day for him to lodge a report. After several emails to Veronica Ramutsindela, management finally approved a swap on Monday 8 June Several more emails later it was handed to Kelly (no surname provided) at Atlas Appliances. After several more frustrating emails, it was handed to management to resolve on Friday 12/06 Today is Day 15 without a fridge/freezer and still no response. I have had to throw away a substantial amount of food and this has put me at additional risk as I have to shop daily for food which is also a waste of time and money. I am shocked at the total lack of efficiency and passive-aggressive attitude. Customer service seems to be non-existent.
