HI-Fi Corporation will only return your call if you bad mouth them on social media

We have ordered 2 freezers from HiFi corporation and the transactions started out great. I received a call from sales to confirm details and agreed a delivery date.

Delivery was scheduled for Friday, 12 June. The delivery only occurred at 19:30 bit at least they arrived.

Unfortunately only one of the 2 items were delivered. No contact information to query this over the weekend and when I eventually got through to someone today, they could not assist as the systems were down

I called 5 times before getting through to someone again and this individual - nameless as did not want to confirm - stated the only way I would probably get a response is if I go to social media. So here I am Hi Fi Corporation - will you contact me now to explain what is going on?
