Poor Customer Services- Extended Warranty Claims

I bought a Hisense fridge from Game Cresta that came with a 4-year warranty. The fridge is less than 2 years old and is already not working. I brought this to the attention of the supervisor at first who informed me to send an email with the invoice/receipt. We submitted this and did not get any feedback from Game nor any email acknowledgment. I then decided to visit the store and discussed my problem with the store manager Trevor who once again asked for the same documents and the fridge serial number. After providing all these documents as requested, the manager assured me that they will revert back to me within two days and that they will send someone to come and have a look at the fridge. He also informed me that he already knows what the problem is with the fridge. Sadly, I have not received the promised feedback nor did anybody visit my premises within two days as promised and another week has now passed with no real help or feedback. I have now struggled in total for more than 3 weeks to get any assistance from Game with no success and as a result, I had to throw out all my meat items amongst other items in my fridge as they have all gone bad and have suffered great losses. This has been emotionally draining and frustrating with no end in sight. I am very disappointed with Game Store as this used to be our favorite appliance store until recently. I have faith that Game can still do the right thing and restore its image and customer confidence by calling me back and ensuring that this matter gets the attention that it deserves.
