can't access

Bait.. need to activate to use.. as long as total amount need to pay is RM20 or below.. Purchase will go through.

I reckon it should be safe to release the booking confirmation page and it's details to them. Especially if for withdrawal, you've already used or will use your personal bank account with matching names on shop back. They already have your name, email and phone number anyways. However, you could still blur out what you want before emailing and if they require otherwise, then you have to choose which is more important.. Cashback or privacy..
