Passport Request. Help needed

[Shamz9]

Hello. My express entry application is approved and I've been asked to submit passport to London Visa office. I applied from Pakistan and cannot travel to UK to get the visa stickers. I can't even send passport via courier as it is prohibited to send passports in mail. VFS global in my country has refused to submit my passport and said that they cannot deliver my documents to London and only take applications for UAE office from Pakistan. They asked me to bring a letter from CIC with permission to submit my passport with VFS Pakistan. I contacted CIC Canada and they said I need to contact UK office directly. Uk Visa office doesn't take phone calls at all and they haven't responded to any of my emails. Now I only have 2 weeks left. Can anyone advise what to do?
