Budgetair.com — Refund not initiated even after sending refund initiation confirmation

I have canceled my booking and Budgetair.com has to refund my money. The cancelation invoice number is BCA- 2941871. It is been 5 months now that I have not received the refund. In last week of April 2021 I received an email from Budgetair stating that my refund is initiated and I will receive money within 10 working days. Now it's more than 15 working days and they are still not providing any answer. This is a serious matter as company is trying to eat the money.
