Have a Care Credit card when making online payments I keep getting warnings that payment was denied due to bad account number. I use the account # on the statements when making payment, and then they charge me interest and late penalties even though payment was deducted from my bank account and debit card which has pushed a balance of $98.00 to over 200.00. This looks a lot like a scam to generate fees and higher interest rates. User's recommendation: Stay away.
