Sir I applied on quikr for online data entry job so I received a call from the company that i have been selected and my task is very easy that I need to fill 700 forms in 6 days and they are not charging any registration fees for this so I thought it’s real. I will get 17,500 for 700 forms but after completion of work I had been told by them that i have submitted two blank form for which I will be charged 4000 and it’s refundable the account has been blocked and for opening the account they are charging it next day when my account open they told me to complete 2 forms which is left during the last form their website crash and they told that i have made the mistake twice I have to pay 8000 if I won’t there will be legal case on me I paid that also. Next day there phone was switch off. Yesterday they talked with me they told Me I will get payment in 7 days but I don’t trust them now sir I m very tensed please take some action on them
