Swiggy — charged even when I have not cancelled the order

My swiggy order number #[protected] was cancelled by the restaurant bt u was charged rs 200.0 as cancellation fee. What type of policy is this. If i had cancelled it then i understand u cn cut whatever amount you want bt someone else may be restaurant or delivery boy has cancelled it n why i hv to pay for this. I want complete refund of 432 rs. This is so cheap.
