My order was for 50 pcs STC 12C5A60 microcomputers. Instead I received six pcs AU3820L. I have no idea of what a AU3820L is but I did not order those. 50 pcs of properly packaged 12C5A60 microcomputers would not even fit into such a small package. Either the seller has made a big mistake or is trying to cheat me. Despite the seller did not replying to my complaint AliExpress found for the seller and refused to reimburse me for my loss of NZ$76.13
