BDA — Online site not working properly

I have been trying to make online property tax payment in the bda site since may 2020 but after entering the pid and receipt of otp, i don't find a link to make the payment. This is still the same till date. That is aug 8, 2020. I am an nri and i have no option left out than making online payment. My parents are old and unable to travel during this covid situation. Please take an action since i cannot pay penalty for no mistake of mine
