Indiabulls Dhani — Refund issue

I made a transaction at amazon and paid money through dhani pay wallet, unfortunately I changed my mind & I cancelled the product for certain reasons.After cancellation the refund was processed by Amazon on 01 July 2021.Now, it has been more than a week dhani is not reflecting my refunded money. The company should remain at their promise.I contacted on Amazon too, they said we processed the refunded amount and they also gave RRN.But when I try to contact dhani they were unreachable.
