Hi Taz,
Are you sure your sis submitted the passport at the BHC? Normally, you submit it at Gerry's. Ask your sis to call at the following numbers:
For PTCL land lines: 090010411
From UK: 00 92 51 2098999
All mobile providers dial short code: 8865
Use the first number if she is calling from a PTCL landline. Use the 3rd number if calling from a mobile phone. if you want to call from UK, use the 2nd number. it takes time to get through to the operator but once you do get through, they tend to be helpful.
Secondly, the email for the Islamabad VAC is
isbvacmgr@gerrys.com.pk .
However, do keep on trying the gerry's number as i am pretty sure your passport must have been stamped by now. Whatever happens, don't give up and keep trying. It took me 2 years and a ridiculous amount in legal fees to finally get a decision in my favor but it was worth it all.
Regards,
Mesam.
