Swiggy — order 2 full pizza from pizza shopee

Address:

21 prem colony near deepak mandir, 131001

I just had ordered 2 full pizza from pizza shopee but i got only 1 pizza but 1 paid for 2 pizza, when i opened this delivery, the delivery boy had gone, i called but no response was there, purhaps it was company no. That what can i do, it was company's default to deliver incomplete order. I want to get my money refund as soon as possible. I ordered food ist time from swiggy... And i m very disappointed. Plz do needful.
