I applied data entry job in quikr. And i got a mail from home solution via quikr. They told me that i have to copy the pdf which they will send me and i have to pay rs. 970 as registration fees by saying that then there will be no charge taken from u. But after that they asked me for an amount of rs. 1850 for providing me that pdf and said that the amount is refundable.
