Zomato — not received my refund after 15 days

Address:

Bangalore, Karnataka

I had received a wrong order so i had raised an issue to zomato. They told me that they will refund my full amount which was 297.93. On further enquiry they told me that they have refunded my full amount.
They gave me rrn no.[protected] to track my amount.
I had ordered on 2nd january 2020 and it's been 15 days but i have not received my refund. This is really worst experience with zomato and i really want to take necessary action against them. The name of the restaurant is dhaba social, beml layout, brookfield, bengaluru.
