The Issue is actually they(The client) is not prompted to enter the credit card details though I(the admin) have given them the access to "Buy their own credits" and "They will pay" and "pay per campaign". When they go to the delivery of the campaign, It does not prompt but directly detects the credits from the admin account. Please get back at the earliest.
Hi Priscilla, could you kindly contact our team with your account details? We'll take a look at your account to determine why the designer account is being charged in this instance. Sorry for the hassle here!
