Electric shock due to faulty charging cable, no buy recommendation!

Very impressed with the price, I wanted a SmartWatch from Foxnovo (according to the recommendation of a colleague) buy.
The delivery time of about 3 weeks from China was in Ordung, the price is really a madness!

Well packaged, after removing the clock made a very good impression,
finally arrived home, I wanted to charge equal to the clock of course.

The charging plug inserted into the socket, and then the following happened:

A loud bang, get an electric shock, and the sparks flew and the entire apartment assurance flew out!
The charging cable completely charred black. The socket broken (see photos)

More I must not say well. Maybe it was just a defective charging cable from a thousand pieces,
(Charging cable, however, was marked for 240 volt!)
STILL RATE I desperately from this purchase AB!

100 you get already an original Samsung Gear V700 from Samsung, the'll try now!

ps
Thanks to the customer, you got very, very quick to reply and immediately allowed the return delivery + price refund
But I have received no answer to how do I get reimbursed the broken socket!
