credit card uncancelled after a promise to have to have it cancelled

<p>I called FNB in February to close my giold credit card (Not the first time). after much delabaration and my insistance that I am closing the account, I was told it was going to be closed. I was shocked first when I saw that there are service charges charged to the account for MArch and as if that wasnt enough, i receive a call today from FNB credic card wanting to add something on my credit card, which is supposed to be closed by now. I am not happy with this service, i dont know what I must do now for FNB to close the credit card because the first time I called them they told me they wont charge me for having it and when the service fees appeares again, I paid the amount and then asked them to close it; but still today it is still active and showing that i owe them </p>
