Bill Me Later PayPal, Ebay Charge a $35.00 late fee for automatic payments they claim they receive 1 day after the due date Internet

I use ebay to do most of my shopping for Birthday's and Christmas.  Recently they added a service where I could defer my payments through paypal to bill me later.  I use my internet bank to make automatic payments and have set these up to be paid the same time each month.  Recently I have noticed they have changed the due date to 1 day past the day they receive the payment and then charged me a $35.00 late fee.  They have done this for several months raking in the cash and since I've had it set up automatically I haven't checked.  I fear this is a scam that Ebay, paypal and bill me later have set up to steal from their customers.  They hope they can bilk $1000's from their customers before they realize what has happened and then it is too late.  Beware of them and check your statement every month.  Customer no service from them is completely unhelpful and accusatory.  I believe they are aware of it and are part of their overall corporate conspiracy.
