Hiboy S22 Wheel with Motor

I wanted to fix my daughter's scooter for her birthday present this year which has an error code E7 and through the chat box recommendation, ordered and received the wrong part, as soon as I received it, reported back that it was the wrong part and requested to return it for a full refund, three or four days later I received a reply asking me to send a video to prove it was the wrong part after doing so and explaining it was recommended through the chat box, was asked for a screenshot of the chat which was apparently erased so no returns or refunds for me, thanks.
