I applied for my passport renewal through VFS at London. Waited 5 weeks for the delivery of my passport which is supposed to arrive at 3 weeks. Then come to know that Dx messed up my delivery. When contacted them, after several exchanges through emails and online chat facility , they finally replied by saying that they sent the passport back to sender. Had to go to VFS office at London for the collection of passport. Such an unreliable courier service, there was absolutely no contact from them during any stages of delivery eventhough I was given my address and phone number correctly on the parcel cover. Checked the track history and it said they made 2 attempts to deliver and calling card was left which is a blatant lie.
