Geek Squad Computer Incompetence

I went to Geek Squad to get my computer checked out because it was running slow, requested my data to be back-up and merge back to the computer (stressed to the employee how important this step was for me since I had important files such as documents and pictures) if needed to be restore. Two days later I get a call asking if it is okay to restore (after I had given the okay at the store the first time), I say yes, and ask to make sure my data gets backed-up and merged to the computer again. Picked up my computer a day later. Computer was completely empty, none of my personal files were there. Called customer service, and asked to get help finding my files. A geek squad technician remotely took over my computer and searched for my personal files, did not find them either. Advised me to go back to the store and have a technician merge my data back to my computer. Went back to the store, spoke to a technician that told me my data was in there, to which I asked him to show me. He could not find my data, because it was not in the computer… Then he brought out a drive and plugged it into my computer and asked if those were the missing files.
