Justby — very bad company

I have taken a service from justby to get customer lead for loan.in starting they told the charge for ther service is 4450 rs
When i deposit the amount they tolde that the charges is increased and you have to pay 1200 more. I told him for refund but the refused to return theb i had paid that money. After full payment they will not provide lead when i called them many times then they provide only 4 lead of customers. When i called the customer they are not interested in any kind of loan and some mobile number are not in service. I suggest every don't buy justby services. This is a fake company and provide fake leads.
