Citibank Consumer Loan Complaint

Citibank Consumer Loan department,

Installment loan Problems when you are unable to pay Florida

I received communications from : - - - - - -. United States ( - ) - And stated that I owed money on online installment loan. I did begin payment on the debt they claimed believing that it was indeed valid. However as time went on with monthly payments they requested payments on an iPhone gift card. I have never ever had to pay any company for any debt with this method. It was very odd and raised an immediate flag. When trying to obtain information on it they went directly into threatening an arrest warrant and court procedure. I want to make sure this is a valid debt and if not report them for fraud.
