Pohunch.com — Order not confirmed even after transaction is successful

I ordered 2 bottles of carbamate forte pcos capsules from their online website yesterday worth rupees 928/- plus 30/- delivery charges for fast delivery. I used the UPI mode payment and even after the transaction of successful, no confirmation message or mail was sent. I tried calling them on the helpline number provided on the site, it always says busy. The number is [protected]. I also tried reaching their support team through mail but later I got the message saying that Mail Id doesn't exist.
Mail id: [protected]@pohunch.com.

I request a refund of rupees 958/- as soon as possible.
