I am facing the same issue. My account is with Bank Alfalah. I requested the withdrawl on 8th May but despite of more than 15 days, payment is not yet received.
By reading the thread, it seems that the problem lies with Bank Alfalah. May you please let me know what reason did the bank provided you for this delayed payment? UpWork has mentioned 0-3 days payment transfer time, but more than 15 days time is too much.
