I had applied for a job in online websites i. E monster.com
And fresherslive (28.04.19). On the next day a company (Magnum technologies) called me and told that
This is a part time job where your job is to fill up 700 forms in 7 days. They also gave me a pdf
Of there official website where they mentioned that you have to pay 4449/- for registration fees.
But after completing my job they will deduct that ammount from my salary. After that all procedure
Had been done successfully including sending my adhar xerox and my photo with my signature.
They send me userid along with password. They told me not to click link on your mobile phone, but which link won't be open they did't mention it.
After tapping a link in my phone, i had given those uid and password, it was showing to me that your account has been blocked by multiple login. I called in customer care of that company, the person (Veer sinh) was so rudeand told that you have to pay 8000/- right now for unblocking your account. They didn't mention it while our telephonic conversation. After complaining to them, they forcefully charged it. If i am not able to give their compensation they will lodge a case against me i rajkot, gujrat and also i have to pay 20000 /- in court. Sir, i am a student. I don't know what to do. They continuously call me for paying there penalty and threatened me. I went to my nearest police station. They told me that is a scam and give a email to head office. Please help me.
