<human>: I'll try to keep it concise. 3 months ago I had to rush my dog to the 24/hr vet. To pay for the visit the vet had to set me up with a CareCredit card. Because of an employee discount they said they'd pay my first payment (minimum).       
Two months went by without receiving any kind of bill, notice, credit card, call, or anything from the company. So I got their number from the vet and gave them a call. Come to find out that they had my address wrong. And I had become delinquent on those two months.     
They acknowledge that they had my address wrong but refuse to talk to me about my "missed" payments.       
I'm wondering if there's anything I can do about the negative effects of missing the payments. Especially because the company didn't even have my address right.

Give me the gist of the text in a nutshell
<bot>: Credit company didn't have my address right, missed payments. What do I do?
