Refusing to close my Credit Card - Keep billing

I am starting to get really annoyed by your *********** service!! I've sent countless emails and made lots of calls to request my account to be closed and nothing has been action thus far.<br> <br> Paid full settlement amount provided by your agent and confirmed account will be closed.<br> <br> I just received a statement to pay a service fee of R25 which will be debited off my account. Do not dare debit my account, I will not be liable for your laziness and incompetence. I want this account closed and proof sent to me confirming that the account is indeed CLOSED with Nil balance.<br> <br> Should the matter not be resolved before the end of the day, it shall be escalated to the ombudsman! <br> <br> FUMING CLIENT!!!!
