Citibank Consumer Loan Complaint

Citibank Consumer loan department,

Installment loan Managing the loan or lease Illinois

I am running a payment behind because originally I was told this loan would pay off a loan I have at Heights Finance. When I sent the check to - it did n't pay them off. So now I have two payments. The manager of One Main, said she could n't do anything. With that said even though I have a payment scheduled in thier system they continue to call and threaten legal action. They have called my employer and sent mail there as well. Now they have also sent an employee of thiers in. My boss and I have both told them not to call me at work.
