How to do automatic bill payments in AWS India?

I am hosting a couple of websites on Elastic Beanstalk. AWS India now only accepts manual payments at the end of each month. They don't save credit cards and Netbanking payment must be manually approved each time. Due to health issues I am frequently in and out of hospital; last time I was admitted for 2 weeks and when I came back, I found my account got suspended for non payment (and the sites went down). This defeats the very purpose of cloud computing if I have to be constantly around for the bill. Is there any way to automate payments?

I tried to get Activate credits but that too got rejected, so I am left with no option now except to make manual payment each time.

If automated payments are not possible, some recommendations on alternative providers will be helpful.
