Hathway — bill paid - hathway saying not received

This is regarding the invoice amount due on 16th september of rs 2829. I got a message on the 8th september from hathway with the link to pay bill. Once i clicked the link, i paid the amount via upi which was an option in the hathway page. I made the payment on the 9th of september. As per my gpay, hathway received the amount on 11th september. Amount debited from my account on 9th september itself.

The customer service team is not helpful at all. They just keep calling to pay the bill. I also received a few emails saying the amount is received however i also get calls that bill not paid. One of the executive even said that i should not have paid using upi since there are some issues, then why is it given as an option in the first place. Attaching my gpay receipt and also the email from hathway that says they have received the payment. Kindly resolve this asap. I am losing my mind because of this.
