Recently I order an amplifier from a store named Electronic Technology Store (France) . The cost of this amplifier was about 9 euros. After 3 days the seller raise the price three times up and told me that he cant send the item I had ordred, because it is out of stock. The amplifier is not out of stock and if you visit his store, you ll see that he sells it about 21 euros. So the seller is a scum and of course gives Bad reputation to Ali express. My order number ID 8172518141487547 So I cancel the order because he Does not want to send the item. I want the item, not my money back. But I Was forced by him, to cancel the order and not loose my money. Fraud. The seller must be kicked out from Ali express I am very disappointment. They must send the item at the price I have order it. 9 euros. Not 21 euros
