Ali Express — Dont receive the order

I bought it twenty months ago and received only 5 of my orders. For the rest of them that I followed up, they told me that it is related to the seller, post and customs.But now the orders have been returned to the sellers, but no one is responsible for this scandal. I can not open a lawsuit and the seller does not respond and says to act according to the order.I have not been able to get my money back yet. Is there really no management?
