damaged phone pictures

I took my damaged phone to Samsung for repairs in November, the technicial told me he cannot open it because its late, he then advised me to book it in and wait for a quotation. I booked it in and the lady who was assisting asked me if my its a new and I agreen she the smiled and gave me a receipt. I received an email stating that my phone was uneconomical to repair because the main board was damaged, I then they said no SUB PBA and SCREEN are also damaged ( which was not mentioned on the quote and raises suspicions ), I went to collect my phone which ewas worse than it was when I took in and asked for pictures, a guy by the name of wayne said the would be sent to me via email, I waited and waited and I still haven't received any pictures. I sent emails I even ccd icasa they still did not get back to me. I want to take this further lease advise where can I get help as Samsung doen not show any interest in helping me
