Account credit card problem

We bought 4000 dollars worth of furniture almost a year ago. We were not happy with some of the products but let it go and paid off our bill in full fully intending to do no more business with that company. We just received a bill in our mail suggesting we owe an annual account credit card fee of 21 dollars. At no time were my wife or I informed that we now had an ongoing account which required an annual fee payment. We would never have agreed to an annual fee type arrangement. I called and explained that we were never informed about a fee that would be charged annually and I was told I had to pay or my credit rating would be affected. Why on earth would I pay my 4000 dollar amount owing and dispute a 21 dollar fee? This is quite an underhanded way to do business and we will not be paying this boguds fee. What are you thoughts on cases like this.
