Terrible service from HiFi Corp

I ordered a dishwasher online. After numerous messages and calls saying it would be delivered but never honoured, it was finally delivered 17:00 on a weekday - I was phoned when they were at the gate, no prior arrangement was made. Needing to get my son to cricket practice, I did an inspection of the packing material and everything seemed in order. The delivery company left and off we went to cricket practice. Later that evening we opened it and saw quite a huge dent on one of the corners. I took photos and closed it up again - the funny thing is there was no damage to the polystyrene or the cardboard box, as if it was packaged that way. The next morning I reported it and was given a reference no. I was asked to send photos to their support no on Whatsapp, which I did and was told I would be contacted. After not hearing back anything for quite a while I contacted their Whatsapp support line again. This time I was asked for the serial no, which I sent a photo of. Then again, heard nothing. I contacted them again on their Whatsapp support line and was told to in future liase with the store. I asked the agent to please read the reference before replying, as I had bought it online, not at a store. Then I was told to phone the e-commerce department. I asked for the agent's name and the e-commerce department's no but was ignored - no doubt due to the poor service I had received.

Can someone from HiFi Corp please give me an update?? I would like to have it exchanged and be able to use it BEFORE the holidays/new year, for which I bought it?

Terrible, poor service from HiFi Corp....... I didn't buy from them for quite a few years because of this and seems I made the mistake once again.
