Non - existing service from FNB Business Enterprise

We signed up for FNB Business Enterprise 2 weeks. Since then it has been one nightmare after the other. We are heading for month end and we are not able to make payments. I have spoken to numerous customer service agents with none of them being able to assist me. I have emailed Marcia Stuart, who set up the system with us, but she does not reply, even though she said we could contact her with any questions. I also asked her to get someone to call us to set up our Sage feed. This request has been made 4 times to her and your call center with absolutely NO response. I have had to complain twice now regarding this service. Is FNB just not able to get this system to work or are new clients just supposed to find their own way around the system, get frustrated, get no assistance and therefore just close their accounts and go to another bank who actually may be interested in assisting us. I demand a reply no later than close of business today. By the way I complained on your website on Monday and nobody has bothered to respond.
