Umer Salam, don't go to that service station again as I believe there could be someone with evil eye (buri nazar) 
So in my case, the problem was with the starting motor so the electrician took it out. Changed the "armature" and installed it back. Alahamd-ulil-Allah, it is working fine.
The cost of the fix includes:
Armature + Installation: Rs.4700/-
Electrician Service Charges: Rs.2500/-
I am including the above details to help anyone guessing the issue and possible cost of the fix.
One question. I remember that before the above fix, when I open the door of my car, I use to hear a beep. But after the fix, it is no longer beeping on opening the door.
My question is do you hear the beep with your Reborn?
Thanks
