Anybody haveSandisk Cruzer Micro USB 4G?

Hello,

I had a Sandisk Cruzer Micro USB 4G that is faulty with very important data in it, and I have no backup for it. I took it to data recovery company and they said that the only possible way to recover the data is to find similiar USB with similar capacity inorder to try to "transplant" the data to its chip; I've tried different shops, amzone, Sandisk company with no success as it is an old USB and not being made anymorre. Anybody can help please.
