Link Utsav — Not received payment back

Hi,
I had applied for HSRP with Colour sticker. Details were filled properly and the payment was also made . Paid On 12th Feb, 2021Method UPI. But I haven't received any HSRP Order receipt from the portal which should be generated at same time. I have searched for the receipt with the vehicle number but there were also no records found.
