shocking service

I have been trying to open an fnb share investment account,after a whole week and a bit I received a phone call today from the share investment department to tell me my transacting account I elected cannot be used as it's put on hold probably because I cannot have 2 cheque accounts on my name. I was then advised to phone the premium banking department so that they can advise which investment account to open so that the share investment transactions can go through there. Upon phoning premium banking,I was advised that I can indeed have 2 cheque accounts and then I was transferred to the investment department who could not help me and transferred me to sales department and from there I got cut off. It's very frustrating to get conflicting information and to be transferred from one department to the other without a resolution.
