AliExpress complaint: The product is not as described

I bought a Samsung S22 Ultra phone After charging the phone, it turned out that there was a problem with the screen and the phone network. The advertisement did not mention that the phone was decrypted, and you may suffer from network problems. I opened a dispute against the merchant and uploaded all the videos and proofs And an email was sent from Ali Express that there is a clear defect in the screen and that a solution must be found, and I suggested that they compensate me partially so that I could repair it, but the merchant refused and wanted a refund for the phone I told them that I paid $150 in customs fees on the phone, and I do not want to return the phone because I will get a loss of $250, including customs fees and shipping fees. The last solution reached is that I will not receive any compensation if I do not return the phone
