I had a company business card until XXXX 2015 when we mergered with another company. The new company I work for does not use company credit cards thus I have to use my own credit card for business expenses. I had made a {$2000.00} payment on my CITI Corp account to free up some credit line for my pending business trip on XXXX XXXX 2015. Payment was credited and I went to pick up my car rental when I was informed that the card would not accept the charges. I called CITI Corp and they advised me that they credited my account for the payment received and had also reduced my credit limit at the same time. I had not been advised prior to this that my credit limit was being reduced. I requested the payment to be refunded to me which they did less payment due for XXXX. Ever since then my statement shows that amount CITI corp refunded as the minimum payment due which I will not pay. I pay an amount similar to what I have paided in the past only to get phone calls stating I need to speak to someone concerning my account. When I do they tell me I still owe more as the minimum amount due for the month.
