Hope good service

Have this knife since 2 weeks and already it works wrong one. I hope this is an isolated case and the seller sends me a new no big ifs or buts. Did he also sent photographic evidence and hope he does not make any problems or demands even more that I'm bothered to send the defective back. Otherwise, the knife 2 weeks was really great! For this 2 stars instead of 1 ... I'll get back as soon as this has been clarified.

EDIT: I agreed that I get a new one. But still waiting ...
2. Edit: I now get the new, everything was great. Deduction for return
