phonepay

Sir,
I take a bus ticket on 21 nov 2017 by railyatri and payment did by phonepay of amount 1529, but after sometime i got a message on my registered mobile no that my transaction has been cancelled after that for confirmation to this massage looked in phonepay apk but there is also shown same (Transaction has cancel) after that i left this bus service and send an email to phonepay about refund amount but that time they did not send any reply.
Now i am calling phonepay costomer care then they say your transaction has been completed and this is system generated sms.
I want to say that this is phonepay pay company fault not mine.
Where as they give cancellations sms sms and showing in phonepay apk.
So i get economically loss of rs.1529/- so please help me for refund amount.
