Swiggy — Cancelation fee charged and cod disabled even though swiggy is at fault

I have attached the photo regarding order. Cod disabled even though swiggy canceled my order. Gave a coupon instead of removing the cancelation fee. Coupon only valid for a month.
Don't have money in bank right now so can't use online payment. And swiggy customer care said will enable only after placing 3-4 orders via online payment.
