Ibibo Group / Goibibo — Travel Pass / Coupons Not Received

I had booked bus ticket from GoIbibo App. My journey date was 07/05/2021 from Jodhpur to Ahmedabad. I opted to buy the ticket with future offers i.e. Travel Passes/Coupons for future use for getting discount of Rs.50 and Rs.25 on ticket booking of Bus and Train respectively. I bought these Travel Passes / Coupons (6 coupons valid for 4 months) for which I paid Rs.99 instantly by adding with my booking for journey of 07/05/2021. I was charged Rs.99 but I did not find any Travel Passes/Coupon in my account to be used for future bookings. Kindly refund Rs.99 or issue travel passes / coupons with revised validity as per your offer / scheme, so that I can use these immediately. I tried to contact customer service phone numbers but none of the number could be connected.
Thanks,
