NO RESPONSE

I called FNB to cancel my debit orders and close my account with them. The agent asked me to send an email and that they could not assist over the phone. It has been over 7 days that I sent the email. In addition i sent four follow up emails and get an automatic response that they will respond in three days. This is false communication as they have still not responded to my email from seven days ago. FNB CONTINUES TO PROVIDE HORRIBLE SERVICE. I want this to be urgently death with.
