Zoho Subscripiton hosted pages

Hi,

We are using your api for subscriptions so users can make payments. For achieving this we always create a hosted page for every customer. 
When it is a new customer, payment form always asks for the credit card details.
When creating a hosted page for an existing customer, payment form sets as payment method previous subscription credit card. Is there a way to avoid that, so that the user is always asked to enter credit card details? 

Thanks in advance.
