GoAir — cancellation of flight at the last moment

Dear sir/madam,
it is highly unfavorable action done from the go air side, u have cancelled our flight at the spur of the moment and even u are not providing us parallel time flight service as we have to continue our journey further . So it is our request either you provide us service in the same period of time or refund our money at todays rate of any other flight as no other flight will provide us flight at the same rate at which we have booked u 10 days ago ...kindly take it into action..quickly ASAP...
