I would not rule it out completely. My SD card was broken (not in half but the bottom part that sticks out of my macbook was kinda crushed). It contained pictures documenting my pregnancy and I was very desperate to retrieve them. After searching online for different solutions and trying different things, Recoverfab kept coming up and I decided to take the risk and send it to them in Germany.
Two days after they received it, I got an email with a preview which had 100 of my pictures! He was able to get my pictures back. I had even lost some pictures in a card malfunction before the card broke and they were also retrieved. There is no charge if the pictures cannot be retrieved so if you have important information on your card, I would try them. You can google Recoverfab to find the website and follow the directions. They also show pictures of the kinds of breaks they can repair.
I know your post is from November but I just dealt with this issue and thought I would share in case you still want to retrieve your data or anyone finds this while googling.
I have a broken memory stick Sony 4Gb capacity that needs to be recovered as the pictures were very memorable and it was taken during my birthday celebration out of town trip. Tried looking for photography centers, misro sd and memory stick manufacturers but to no avail. Until i found Recoverfab and Mr. Leopold Heirsche, who is probably the only expert globally. I took the risk of sending the broken mem stick to Germany and was hopeful until I received email from Leopold that he was able to recover the pictures. This would entirely suprised my whole family after being disappointed that it was broken. Mr. Leopold made us all happy and no one ever considered that it can still be recovered. Again our gratitude to Recoverfab and the man behind it, Mr. Leopold Heirsche, Truly a remarkable save that we will not forget!
You can try fixing the SD card and also can recover the data or can repair broken loch on SD card. I used the SD card for my camera. I had many pictures stored in the card and by mistake the card was corrupted. So I needed to recover the data. For this I took help of Easeus Data Recovery Wizard Free Edition. May be this will help you.
Try out if this works:

3) Place the clue along the along the paper clip.
4) Press the paperclip piece firmly against the area on the SD card.
