Swiggy — I didn't receive the ordered items

Address:

manesar, 122051

I've ordered items from dominos, order i'd is [protected] from dominos manesar to sec 1 manesar.
After half an hour status is shown as delivered but i didn't receive the items at all. When i talk to swiggy exercutives they keep on giving me the numbers to call. When i asked for the refund they are closing conversation.
When i paid to swiggy, why should i call other numbers.???
I want my 620 rupees back.
I don't how swiggy is going to do it.
