Can anyone help me how to know about the real buyer? Some buyers played with me that completed the work and shown him. He told me your work is great. When I ask to place the order he told me my wife is not present at the house due to cardholder. I sent offer more than six times but didn’t except once. I completed the work in three days and he wasted my three days.
Before buyer place an order for your service, you should not keep your effort into action. Doing so, before an actual order is nothing but foolishness. You should only trust and start work for the the buyer after placing an order. Otherwise, you may be fooled by the buyer as has already happened with you.
You should not accept any excuse for not placing an order by the buyer and start working
You can always send mockup but never deliver the actual work/solution.
