Received not original equipment and problems of withdrawal

In my case (Global Trade), it was definitely not the original equipment. I ordered 2 pieces, each charging time 4h 2h instead of like the original.
Requested immediate withdrawal and sent equipment back. My withdrawal was ignored and has instead sent me supposed replacements that never arrived. Had me the money at the end of Amazon fetch directly what worked super. The traders threatened me now but with action, because I would have withheld his replacements.
