Delivered on October 18 doesn’t mean that officially received your passport in the office, just call CIC the agent will tell you when did they received your passport officially at CPC office. I send my passport on October 2 and delivered on October 4 but officially the visa office received my passport on October 6I called up 8882422100. According to the automated message, my application has been approved and they are waiting for my passport. But I have already sent my passport and it reached on 18th October. WTH is going on!!!!!
