Pair of Nike Wildhorse 7 has not arrived after 1.5 years!

I ordered and paid for a pair of Nike Wildhorse 7 shoes on 6 April 2021, and it was shipped and received at South African customs on 14 April 2021. RunnerInn order # 22553164. Due to covid it was said that it will take unusually long as there was a big backlog at customs. RunnerInn, under TradeInn, does not provide any contact detail so that I can find out if the parcel was returned and if they could resend it to me. The chat bot just says there is no information wrt the order or tracking nr (RU870316627NL I really wish that I could receive my shoes.
