unable to download invoice for CA membership fees payment 2019-20

Hi all,

I paid my CA membership fees on 21st aug 2019 for FY 2019-20. I didnot check for invoice at the time of payment. Now I tried to download the invoice by whenever I login it logs me out saying your membership fees is already paid.I tried all possible services from my end to download the invoice as I need to claim it from my company . Not sure if I am making a mistake or ICAI website has an issue.
