Hi-fi Corporation: Bad customer service

I bought a tumble dryer from Hi-Fi Corporation in December. It was delivered on 16 December 2019. Upon unpacking the dryer I noticed a dent at the back and a huge dent on top of the dryer. Since then I have unsuccessfully tried to phone them - the line cuts out after a number of rings. I have emailed a few times. No one even bothered to respond to my mails. I want the machine replaced.

I have received an automated response to my various emails:

Hi there,

Thanks for your message! At HifiCorp., we’re dedicated to awesome customer service and are always looking for ways to improve. One of our representatives will make contact shortly.

Awesome customer service - I wish ...
