Wireless charger power bank magnetic
Order id: 8151248460193364

I received a broken charger from the seller. The tip it broken and when you put it in your phone it just gets jammed in it. I have complained to the seller but he not helpful and now not replying back and blocked my messages. I have complained to Ali Express and they said to return the item. I received a return label but when I took it to the post office it didn’t scan. I complained to Ali Express again and they said to take it to another post office. I did this and they were not able to scan it aswell. i have been chasing this up with the seller and Ali Express and neither seem to want to help. I put in a dispute which was rejected saying the pictures dont reflect the item is broken, when clearly it can be seen from the pictures. I Appealed but thats been rejected because the time has ran out for getting a refund.
