Your deposits were indeed refunded 20 days ago. Unlike regular transactions, in case of a refund, we don't get a "special" confirmation from the bank if your account was credited or not. It will appear as "done" in either case.
The moment you contacted the finance, they opened a query regarding this issue- it takes time since it goes from our bank, to correspondent bank, to your bank and then the reply goes all the way back.
I will update you when we get a reply.
If you can take another look: The refunds can appear in 3 different ways:
can appear as cancellation on the return date (around 8th of feb), or on the date that the original transactions were made, or just the original transactions deleted.
