Bone in burger

Last week Friday I bought a KFC box meal, I chose the zinger burger with zinger sauce. When I got home I realise the burger was pretty saucy and I decided to eat it with a knife and fork instead. While eating the burger I struggled to cut through the one section, when looking closer I realise it wad because the burger had a wing bone in it. Surely a fillet should not have a bone in, if I bit into this I could have broken a tooth.

I have sent KFC customer complaints an email on the same day and followed up with 2 or 3 more mails but have not had a response.
