@JenoP I have been reaching out to the chat support team. I have had good responses from them on functional issues earlier.

On this front though, there isn't much that they are offering.

When the credit card bit failed, I was told to wait until the account goes into 'cancelled' state as that is when things would work.

Now that it is in that state and I have only read-only access, they keep repeating the instructions on entering netbanking details etc which I have done several times.

When I explicitly ask for this to be escalated, they just came back with opinion from 'higher team' that I should use a savings account.
Worse, after spending an hour on the case discussing, the status gets closed without resolution.

I have done two one-hour sessions on consecutive days after getting into this status. 

What do I need to say to get this account into the 'affected users list'. The chat support people haven't spoken about this investigation on errors. Perhaps they are unaware.
