hi needvisa!
buddy in any case i think its better just take print out from tcs website(
www.tcs.com.pk, put ur tracking number there it will show you the delivery date) scan it and send in your email stating that you want to make sure your documents received in-time as somebody from their office said it was received on 23 nov 2010 so later they can't make any problem you crossed the deadline. this is my sole opinion and rest is upto you to decide.
good luck!!
