Mobikwik — Delayed Refund and Technical Issues with MobiKwik Zip Pay Later Wallet

I ordered a product from Myntra on July 10, 2024, worth ₹930, which I paid for using MobiKwik Zip Pay Later wallet. When I returned the order, I received a refund of ₹911.74 on October 1, 2024, at 08:24 PM back into my MobiKwik Zip wallet. However, when I try to withdraw this amount and link my bank account, the transaction remains pending and fails.
Yesterday, when I contacted MobiKwik customer care, they asked me to raise a complaint and assured me that my refund would be processed within 24 hours. However, when I called them again today, they informed me that due to technical issues, the refund is not being processed. Additionally, they have blocked my Zip wallet for quite some time and mentioned that the refund will only be processed after the wallet is unblocked. I have no outstanding dues on my Zip Pay Later account.
I have been requesting a resolution, but they are unable to provide a specific timeline. I am extremely frustrated with this situation and request your assistance.
