Refusing to return a defective productI've bought a thunderbolt dock station in AliExpress that looked very at the advert, multiple hdmi outputs, many usb 3 and usb ports, a perfect solution to connect my laptop with a single cable to my working station. The bumpy road started with the dock station coming without a power adapter. To be fair, the advert didn't show it, but I contacted the seller and asked to include a compatible one , what I was happy to pay extra. They didn't and as I suspected, not every power adaptor could power the dock. They refund me part of the payment as a compensation so I could buy a adaptor and was happy with the solution.Recently I realised that the muse was lagging too much when connected to the dock and so the keyboard and to make matters worse, when connecting 2 external hard drivers, the dock would simply disconnect and stop the transfer in the middle, risking a serious damage to the memories.I've contacted the seller arguing that the item had now a different defect and submitted some evidence. He agreed and offer me to return the item, but as I had a dispute before, he advised me to contact AliExpress for that. Did so and refused my claim offering me USD 7 in compensation, on a item that coated me 60.Worst platform ever. Moving to temu as those guys are not reliable at all.24/05 Update I've submitted a video and pictures showing the problems to AliExpress and they were not sufficient for them to recognise the issue. I've produced 2 more videos following their requirements but by the time I've submitted them, 3 days later, they've closed my case.This is AliExpress customer service, too slow to refund you and too quick to get rid of your case.
