Digitlogics — Issue that they're not sending my money back

I have done a purchase from Flipkart on 15th June 2018. I have cancelled my order the same day. Flipkart took no time in refunding my money back. But PhonePe App is taking time now. They have not refunded the amount yet. After so many days Why PhonePe App is taking too much time to refund my amount? I want to know the reason behind this late? My ticket number which I raised is 15870533.
