Game not helpful at all.

I bought a Defy fridge at the Game store in King Williams Town on 06th June 2018. This fridge carries a five-year warranty. It has been fixed in the first year as it was leaking water. The fridge has stopped working again and the invoice that I received when I purchased that unit has faded out. I have logged a call with Game Customer Service on the 07th December 2021 to get a reprint and it has been a mission to get that done. I spent the whole of December without a fridge. I spoke to the store manager at King William's Town branch over the phone as he refuse to see me while I was in the store and he promised to get back at me of which he hasn't done that and now he has stopped taking my calls on his cellphone. I have sent emails to customer service and they also have not been helpful as they did not respond to my emails. The only assistance I need is to get the invoice so that this fridge can be repaired.
