I bought a used Intel Core X9100 processor from the CPUIT store. I asked the seller many times to send me a working processor. But I got a processor from them that doesn't work. A very good service center was unable to install it and/or get it to work. The seller categorically denied a peaceful solution to this problem and insisted that he thoroughly test all the processors, and now I myself have to prove that this used processor does not work before he will accept a return. He did not bother to answer me quickly, put off solving this problem in every possible way and only at the last moment answered with short general phrases. I started a dispute with AliExpress, as a result of which they demanded additional evidence, such as videos of scientific experiments and reports from official service centers with all seals and signatures valid for China. But it is obvious that no legal document I can obtain will be useful in China. I had to close this dispute and start a new one, saying that I just want to return this processor in the packaging that I received. But AliExpress only agrees to a very limited number of days to start a dispute, and what the situation will be with returning the processor without strong legal evidence to China is obvious. Now I have no working processor, no return address from this seller, no money, no trust in AliExpress. This is a clear violation of the fundamental rights of customers in any country other than China. With AliExpress you will be deceived by very experienced combinators.
