Oyo Rooms — did not get refund for the booking that I cancelled on 01/11/2019

I had booked in oyo rooms - 26243 lake market kalighat on 08/09/2019. Booking id alim-4751 with check in date 07/12/2019 and check out date 08/12/2019. I cancelled my booking on 01/11/2019 for which i got a confirmation mail from oyorooms on the same date stating that amount of rs. 3184/- will be refunded within 7-14 working days. However, even after 1 month, i have not yet refund of my amount to my a/c. I have even lodged my complaint with them but i have not got any satisfactory reply from them. I have even attached my credit card statement for the last 1 month as an evidence wherein there has not been any credit of rs. 3184/- during this period. I had asked them to provide me the unique transaction reference no. (Utr no.), date of transaction, bank a/c and ifsc code that has been debited and bank a/c and ifsc code to which the amount has been credited. But they are not providing me these details. Please help me in getting refund of my money into my a/c.
