Sandisk SSD Data Recovery

Hi, 

I have sandisk SSD while I was cleaning my desktop I connected the SATA power cable in the wrong way I think and after I turn on the computer smoke came out of the power side, my life in this SSD I found a local data recovery company online  NiwTech https://www.niwtech.com to have a look and after i gave them my SSD they contacted me the next day saying one of the  NAND  is burned and it’s impossible to recover my data at all. my question is that right or I have to look somewhere else?

Thank You  

Sadly, No,

NAND chip is where all data is stored, but would you care if you take picture of the internals of the SSD you own?
