No idea about Shaheen but i have had experience with AIG (closed business in Pakistan), Askari and Adamjee. Found AIG the best amongst all. Then switched to SGI Insurance (Nishat Owned) and have found it THE BEST amongst all i have ever tried. Their customer support is outstanding and their network is really wide. So thats my recommendation as their rates are also competitive. You may call Usama at 03334391533 with my reference
