Aliexpress "******" me

I purchased several items (+-10) from Aliexpress, the products were delayed , there was a price increase on one and when i requested a refund they refused to initiate same, and i never received a refund for that purchase, I cancelled some products and in the one instance they deducted $10,00 from the price that i paid. They do not have an office in South Africa so we cannot go to them and complain, when we send emails , they respond several days later with a robotic response. The robots don't know how to answer my queried so much so that i cancelled all my products and didn't receive a cent bank, i spent +- R1500, 0 on purchases
