Dear sir,
We are not getting clear and service from that postmaster and he's not providing to us. Last month we got letter from bank by he didn't gave to us then we asked with bank that time they said we already sent and it's the fault of postmaster. See this is the serious issue if we won't pay loan and all. And even he called us to post office to pick that notice other wise he'll not come itseems. These are problems getting from him. So please provide another postmaster to our village. Waiting for best response
