Oven Story — refund not done

Address:

39-Shiv Darshan Soc.2 ,Causeway road, Katargam-395004, Surat, Gujarat, 395004

I have ordered pizza's on 31/12/2019 from oven story through google pay and due to my reasons i cancelled the order after that the employee told me that the refund would be re-directed in my bank account within 7 working days.
I didn't received the refund till date.
I messaged the employee twice but didn't receive any response from him.
I also tried to contact them but was not able to do it.
