This company gave me a work to fill 1200 forms in 12 days but they gave me 10 days time.
Even though I completed the work.
It's perfect.
But they are saying QC Check is failed you didn't recahed the accuracy so you have to pay admin charges.
If you fail to pay it you have to attend the court and have to pay 20000 rupees it seems.
Please solve this...
