Fake USB Drive Size and Low Speed

[Googleuser1]

Hi 
I bought a HP v220w 128gb pen drive in April this year from flipkart, back then I used to it store some data which was about 50gb and it worked perfectly fine. Few days ago I tried to put again some 20/30 GB of data on it and it did, but when I tried to see the files I have uploaded, some of the folders were empty. Today I tried to format it but it only supports exFAT and the upload speed has been reduced to about 1mbps. I have read seen something like this on a youtube video in which he said this was a counterfeit product. What can I do now? 
Thank you
