Swiggy — my order had missing item and refund was not made for it (swiggy order id : [protected])

Address:

560076

I ordered 4 items and one out which was missing. Despite of sending multiple mails to swiggy support, no corrective action was taken. All kind of out of context excuses was given to me. I lost money and my time following up with swiggy. They are blatantly telling me that refund will not be made for this and we have made a note of it. There customer support has not given any reason behind it.
