Simplilearn — Refund Completed but not credited

My refund was completed on[protected] for the DevOps course i enrolled in, As per Simplilearn the refund is already completed and is with Shopse. Once i contacted Shopse they told me the refund failed due to bank issues and have been sent back to simplilearn. They even shared me the failed transaction ID. I have been hanging in between Shopse and Simplilearn as whenever i try to contact Simplilearn they tell me to contact Shopse and whenever i try to contact Shopse they tell me to contact Simplilearn.
I already opened a ticket with Simpilearn but it's been almost 5 days still there is no reply. Everytime i try to contact Simplilearn they tell me to wait for 24 hrs,

I have shared them the proofs as well about the EMI's getting deducted. I am helpless as again and again I am just being asked to wait or call Shopse and vice versa.

Refund ID from Simplilearn: 21214
Failed transaction ID from Shopse: S[protected]
