Swiggy — do not refund the amount aon time

15 days back, i ordered masala dosa and idli from minerva express on swiggy and what i got was just the dosa and that too onion dosa. Even if it was a mistake but when i complained about it, they told me that they will be refunding the amount charged from me since it was there fault to send the wrong item. Since then, i haven’t got my money back and today when i tried chatting to their support bot, they didn’t even initiate the conversation. It stated that the issue is resolved from their end. What kind of customer service is this? #patheticswiggy
They should learn how to handle customer grievances faster. Even if the amount of the item is not too huge but they cannot get away with it.
Please file my complaint against them.
