I donot think they are tracking number on our PP. but in my experience, first time the lady took the phone she was very kind gave all the possible information.
but second time, she was really rude. she asked my SL date, said 'no not yet processed, i cannot tell anything else' then just hung up the phone, nothing further.
even after they cleared mentioned in their website that, 'we cannot provide any status on your visa processing', we are keep calling, making them irritating. thats why they are being rude now a days.
