HiFi Corp is a disgrace to mega corporations

I made a purchase online(5th of June 2021) of a washing machine, at the time of the purchase there were 2 of the product in stock. I'm now receiving calls advising that there is nothing in stock and I have to request a refund which I will get after a minimum of 7 business days with a maximum of 14 business days, or the order will get cancelled in 5 days as the new stock will arrive in about 3 weeks. This product was bought to assist my sick old mother, especially since it's winter, so the fact that we now have to wait a minimum of 7 business days to get a refund before we can do anything is really causing us a massive headache. The managers I've had a chat on the phone with offer no solution except for a refund(which is not what we want). I've personally had to call multiple stores and found that they have 6 available in stock in Johannesburg. I firmly believe that if they care enough, there is a way to communicate with other branches or someone higher-up to override the current order and reroute it to make the purchase so my mother can finally get a bit of rest. This is really upsetting and I hope something will be done as soon as possible.
