Ola — not provided invoice copy for payment done

Dear sir /madam
I had taken a ride on a cool cab through ola on 31st may 2019 08.47 am. The fare was rs 469. Upon reaching destination i paid cash of rs 505 as driver demanded extra 35 rs for toll tax. As i was in urgency i left and he told that combined bill will be received through mail..
I followed up many times for the gst invoice but received mails that invoice cannot be generated for xyz reasons.
This is not accepted. If i have booked cab through ola platform, i have a right for invoice because i have paid money for it.
I am attaching screenshot of ride and the mail received from ola.
Kindly look into this as this has caused a huge convenience and loss of trust in online platforms.
