Amazon India — amazon.in order #[protected]

I ordered philips beard trimmer of rupees 900 on 13 feb 2018 through cod. I received this order on 16th feb. But instead of philips trimmer they send me cheap quality nova trimmer. I call their customers support team they told me they will give me my refund. But today when i check my amazon account i found that this order is cancelled. So where is my order and where is refund??
