Drivezy — airport ride

I have booked an drivezy airport ride starting 17th feb 2019, 08:00 am. My payment has also been made with amazon pay payment id: pay_bwh7lj5vkasvke. But i have neither got any booking id nor it is reflecting it in my upcoming booking.
Neither their chat nor call support is responding. Most unprofessional behaviour of a company towards its customer.
I want my issue resolved at earliest.
