On XXXX XXXX, 2015, I charged XXXX to my Citi Health Card account for vetinary services rendered at XXXX XXXX XXXX. I was to receive 0 % interest if the credit was paid in full ( do n't recall but between 1 1/2 to 2 years ). When I received my XX/XX/XXXX statement, I noticed an interest charge of XXXX. I called CITI to dispute the interest and was advised that XXXX XXXX XXXX entered the transaction wrong. They said that the veterinary center did not enter the promotion code. I immediately called the veterinary center and told them about the problem. 
The veterinary center called me back when they corrected the issue. I continue to receive finance charges despite numerous calls to CITI Health Card to resolve the issue.
