I paid bill amount in phonepe application and they have provided merchant reference number : phnn1901191303017570390480 and they are like transaction is successful. This is the response they have provided me. Please look into this.

Dear syed,

As per our telephonic conversation regarding with bill payment of rs.8444.[protected] please note,
That the payment status should've updated within 4 days after the payment. Some of the billers will update their portal in the next billing cycle.
