Further to my previous review, I declare to the world that three and a half months, a couple of internet reviews and a police complaint later I got my money back from Vijay Packers. God bless them.
The moral of the story is: you can use them, they do the job reasonably well, but don't give them any money unless you are sure it is due (and before they've done the job to your full satisfaction) as they are not professional enough to handle bona fide complaints.
