Income Related Subscription

I am on Discovery Key Care Plus option. I was asked for bank statements and salary advice slips which i mailed to them. Then i get a response like i need to do an affidavit to declare other credits in my bank account. I think this is crazy. As long as it is not part of my income they should not be concerned with it. I received a message to say my subscription will be based on the highest income band.

It is a pathetic state of affairs when *********** employees of Discovery tarnish the Brand.
