Order not fulfilled

I ordered a scale on the 11 June 2020 and paid for it online same day it was set to be delivered in 14 days which would be end of June. When I track my order it has been sitting on "order placed successfully" but it wasn't moving to other stages. So I contacted hifi corporation's customer service department and it turns out they can't deliver my order because it's out of stock to my surprise they still had the product advertised on their website and on the other hand they only sent me feedback just after I had to call them and query about where my product is sitting and when I should expect it.

I received an email from someone called Mbhali who was rude enough to just offer me a refund even though I had asked that they offer me a similar product to what I had ordered this person just ignored my request and ordered me to send my banking details for a refund that will take another 7-14 working days, why should I wait this long to get my money back? And for customer service sake why didn't they opt for supplying me with a similar scale to what I have ordered like I asked since I have waited for so long already.

What an appalling service I have received and not to mention poor customer satisfaction from their staff.
