AliExpress complaint: Paid double VAT and Refusal to refund

I have ordered 5 lipsticks. After receiving the order, I had to repay VAT plus customs clearance fees (5 times more the price) per lipstick. As per AliExpress politics, you should get a refund. I have contacted at least 5 agents and sent all the necessary proof to them. From the escalation team I always just receive an email repeating that they need proof (like a prebuilt email). This being the main reason going back to the agent and resending them the Invoice proofing the VAT payment, order number, package or tracking number, custom clearance bill mentioning the VAT plus fees.
This all due to paid and non declared VAT from the seller. I don’t know what else to do as this is a legal matter that is clearly not being respected by this giant company. I hope other clients won’t have this experience.
