More than 3 months since I ordered and received nothing as yet and owner does not answer my calls

I placed an order on 13 November 2022 and had numerous conversations with the owner always promising my order will be shipped the next day. Then in between you cannot get hold of him. He promised me again on 12 January that my order will be shipped the next day or two and then from there I cannot get hold of him and he does not reply to my messages. I have not received my order and it has already been 3 months.
