Overnite Express Courier Services — Delay in pan card delivery..

Dear sir ,
I am Dr.Shaik Mohd Younus from hyderabad (Bazar Ghat H.NO.:[protected]/A,First floor). I applied for my pan card on 10 feb 2010. And i got the status that it has been dispatched on 17th feb to hyderabad and will be delivered the next day, But i did'nt get any ,so i checked the status on overnite courier site with my Airwaybill No.: :[protected] and it showed " Out for delivery on 22nd feb ". I got a call from the delivery person named SRINIVAS with mobile number [protected] that he will be delivering me the courier at 4.30 pm . I stayed back at home waiting for him .But he didnt come and when i called back him he said he left and will be delivering tomorrow after 5 pm .Next day also I waited ,he called me at around 5.10 pm and said he is in mallepally and asked me to come and collect from there.I said come home its nearby bazarghat he said ok fine.I called him back at 6 he said he left and will be coming tomorrow.Today i was waiting for him.He called me at around 5.30 pm and asked me to come to nampally chowrasta if I want it now or else he will come after 1 hour at my place. I then called him in an hour and he said come and collect at the nampally chowrasta or else he will deliver tomorrow at 2pm...This Delivery person Srinivas showed me a very bad attitude and hang up my call saying " Saab mein kal aataun bolana Phir... "
I then called up the hyderabad overnite courier customer care but no reply was there...
I am a dentist by Profession and i have to go to clinic daily .. Because of this person Srinivas I had to cancel my patient appointments for 3 days ...Atleast if this person cannot deliver on time , atleast speak properly to the customers but he showed no signs of curtsey only ...Please look into such irresponsible person's behaviour and please deliver my PAN Card at my address[protected]/A,First floor Bazar Ghat as soon as possible.
Thanking you
Yours Sincerely
Dr.Younus
