Bad,bad online service,with non-existence customer service

I'm very disappointed and annoyed with the level of service with this company. Bought sneakers online on the 29th November 2021 and to date have not received my order. And their response on call, email and online portal is close to non-existent, because you get the same old response that your query has been sent to the relevant online department and they haven't responded. Like online is supposed to be all about convenience and rapid response. They currently have my money, apparently the sneakers are no longer in stock. But no one called me to notify me, I had to call again only to get that response. Orders take 5-10 working days (that's a joke), refund supposedly take up to 7 working days. So the will have my money on them for almost a month, while I don't have what I bought. I have never experienced such poor level of service from an online purchase
