This is a complaint regarding a fraud data entry company named aptech solution. These people mailed me a workload containing 100 pages to type and claimed to pay me 180 rs per page.
I completed the work within the given duration but now they have replied to my work that it doesnt match the required accuracy and i have to pay a fine of rs 6999/-
i have recieved a mail from a email id with a fake lawyer name mayank sharma and is threatening me that he will file a case against me under different ipc sections if i dont make a payment.
I would like to file a complaint against such fraud company.
Please take a serious action against them.
