Synchrony Bank Amazon Store Card One-time Payment vs Recurring Payment Internet

Synchrony Bank is quick to draw you in for the Amazon prime store card, but what you don't realize is, they don't understand the differnece between a one time payment and a recurring payment.  They try to say that if you make a one time (additional payment on credit card), prior to the due date, your recurring payment will be reduced to only make the minimum amount owed that month.  

For example, minimum payment is $75.00, you make an additional payment of $50 prior to your due date and your recurring payment is $75.  They only take $25 for the recurring payment because the additional $50 and the $25 is equal to your $75 payment.  Then they can add on additional interest.  

Would not recommend you apply for their card.  Customer service is terrible and they just don't care what you have to say, it's as if their response is scripted.
