No product,no refund

I did a transaction with Jon Pierre in June, paid upfront for the goods and waited. I received the first half of the order but the second half never happened. Jon Pierre agreed to refund the second half of the transaction on 21 July 2020. I have had to ask him for the refund 5 times since then and tonight I called him and he made another one of his false promised that he would look into it tomorrow and put the phone down in my ear. People shouldn't trust Jon Pierre as he is not a man of his word.
