Synchrony Bank Credit Card Complaint

Synchrony Bank Credit card department,

Other fee Ohio

My dog had to undergo emergency surgery last year. To finance it, I opened up their recommended CareCredit account with Synchony bank - first year 0 % financing. I made my payments throughtout the year, realizing that I needed to do something with the remaining - balance now. I pulled up account - they just added a - interest charge!! I realize that this is probably in their fine print, but this is grossly taking advantage of people who can least afford it at a time when we can least afford it. I 'm good for my debts, but this is ridiculous.
