Thank you All
Here is an update on this
client after so many messages responded me that he is busy in conference and will talk to me today and today after waiting 4 days, he cancelled the order saying that he got his answers and dont need services any more.
After i accept his cancellation, my ranking went down
In this whole scenerio, client was ignorant , did not share information with me to work, disappear and then cancelled the order before sharing any information and allow me work.
I complained to fiverr but this one order has destroyed my whole 6 months effort and i made no mistake in this. I wish fiverr remove this impact from my profile.
