Children bike

We bought the bike our son for his birthday. When unpacking the handlebar was only loosely attached to the stem, so that (and beautifully themselves painted) handlebar when lifting out of the packaging has been scratched. With appropriate knowledge I had the bike lifted cautious or otherwise.

After only two days, the rear started to block. The seller (liquid-life-de) has promised us to send a spare. However, to date we have not heard from him. The FA Bachtenkirch we have also given notice, but we only received the message that we should turn to the sellers. Finally, we are probably the rear wheel must be repaired at a bike shop, which should not happen with a new bike.
