The gamepad was confidently transported to Hong Kong for examination by the service department of Sony, which is located in Hong Kong. The courier came to the house just because the homeowner requested his services and removed it without any issues. After a period of time, the service department came to the conclusion that the device could not be repaired. They then mailed a certificate to confirm their decision, but they kept the gamepad that was unable to function for "safekeeping." You are instructed to take this certificate along with you when you go to the seller in order to replace the goods that are covered by the guarantee. However, when I contacted the technical support of the Amazon marketplace with this question, I received a refusal to replace it. The reason given was that a return is only possible while the product is still under warranty or before the product's expiration date. The normal period of warranty coverage offered by Sony for gamepads is one year. Although I didn't buy mine until the 13th of February in 2022, the warranty year is still valid. I don't comprehend the rationale behind denying me a replacement item. If it were an actual store, I wouldn't have a problem doing this, but when I try to do it through Amazon's online marketplace, I get an error message every time. That is to say, I am currently without the product that I paid for, which I could even offer to have repaired in exchange for monetary compensation, and there is no replacement available since the retailer is refusing to provide it. Just outstanding!
