Pending funds since last week

Hi everyone,
I am new freelancer and transferred the funds 1st time to my account, according to my research most of the people said that payment transferred within 2~3 working days. But almost a week passed and my funds still showing pending in payphone.
Can anyone en-light why this happening and how much time it will take to clear my funds?
I will be thankful to you everyone.

Regards
Asfandyar (Mr.)
