Swiggy — payment issue - refund & coupon

It is regarding an order placed on oct 20, 2019. Order # [protected] for an amount of rs. 425 which was accepted but not delivered hence customer care refunded the money as a coupon with an addition of rs. 50 more total = rs. 475. I had used this coupon to place an order on oct 24, 2019 to order a pizza amounting to rs. 179 out of which only rs. 20 was paid by me and the rest rs. 150 deducted from coupon of rs. 475 (Food475). Technically the remaining amount with swiggy under my account should be rs. 325. Today, i was trying a place an order for rs. 150 and tried using the remaining amount but it was a nogo. I contacted customer care of swiggy on it and they said the coupon (Food475) can be used only once on any of the order thereby stating that my money of rs. 325 cannot be used anymore. I feel cheated as this is not right and companies like swiggy are giving a service much needed but are also exploiting people with policies as these. If this was the condition then the executive who refunded the amount to me should have informed me about it and then given the refund in the form of coupon but he went ahead with the coupon without informing and double checking with the customer. I feel cheated as the executive i chatted with a while ago said this is it and nothing can be done about it.
