Ola Cabs — invoices for the rides

I want the invoices for the rides i took for the period from 1 aug, 2018 to 31 dec, 2018. These rides i can see in my ola app but i am not getting the invoices for my rides after following the required steps. I have highlighted this to ola support a number of times and requested them to provide the invoices over my email. But they always keep sending the steps to be followed to get the invoices from ola app which is of no use to me as explained above. My recent complaint number is[protected].

I want the invoices for rides from 1 aug 2018 to 31 aug 2018 on my email id as i am not able to get it by following the standard procedure of getting it though app on my own.
