Faulty Razor

I purchased a packet of razor blades that is made by the company. The blades was faulty on the Razor and i cut my face very bad. I did get in contact with the company and did send them the faulty blade. I have now send several Emails to them but to just get no response for the last three weeks . It feels if they are just ignoring me and hope that this issue will just disappear. I have the photos of all the blades and my face and if i do not get any response will have to seek legal help.
