Incomplete refund of transaction amount through Phone Pe

I did a transaction on Phone Pe of amount Rs. 449 and the transaction was not successful. The next moment I receive 2 messages of Rs 50 and Rs 100 respectively. Then another message that Rs. 299 will be reversed to my account in 7-8 working days. I called customer care and there the executive kept on explaining to me that the amount is deducted bu Phone pe and refund is in the hands of the operator. The transaction id for phone pe is N1805042137078117. My point is when the transaction failed the complete amount should be refunded.
