[Resolved]  Airtel — Poor network reception and GPRS speed

I m a prepaid subscriber of airtel from mumbai region.I just wanted to complain that i am getting very less signal reception at my place even i stay at 6th floor and at 5th floor i am out of coverage area.So i am missing many important calls because of this .Other service providers like idea,vodafone,aircel,loop,tata are providing full network at my place and even on ground floor,so whats wrong with Airtel ? I am requesting airtel to build a cell phone tower near to our place as soon as possible,otherwise Airtel would be loosing 20 prepaid subscribers from my society.And also GPRS speed is wrost in mumbai region.I am providing my address and contact details below..Dont try to contact on given cell number because i have kept it switched off.
