@Monu , it is possible to use a voucher to add funds to the account. However, I don't think it is possible to subscribe without a payment card on file. You might be able to ask support to renew the account manually for you each cycle. It would be a painful exercise and your account would go into suspension each time. The choice architecture chosen by this service is to have customers be subscribed all the time.
How to pay monthly subscription without adding credit card? I don't want pre-authorized payment, I want to pay as and when needed.
You need a valid debit / credit to activate your PM account initially...but once successfully activated, you can disable Subscribed (Autopay) and use payment vouchers going forward.
