Aliexpress is a ****

Aliexpress is a ****. I ordered a set of chairs and table, for R6800, which was paid directly on their website.They said they deliver within 24 hours. After 3 days they tell me that I need to pay R1360 shipping fee, which will be refundable on deliver of my goods, I paid that, which they confirmed that they have received that R1360. After 24 hours, I ask where are my goods. They say that my goods will be released from their store as soon as I pay R2670 refundable fee which acts as insurance to my parcel just in case of transportation damages. Even now they are re still saying that they will hold my parcel until I pay R2670. I wanted my money back and they refused to cancel the purchase.
