Statement and login problem

I have phoned many times to MFC to get my monthly statement they sent me. I am unable to open it. I am told I can get it on the website. I do have a username and password. When trying to log in, it says immediately there is a problem with my username and password. When click on "Forgot details?", it immediately says "Timed out". When I phone MFC to ask about this, they simply say they do not know why. They then refer me to the Nedbank mony app. It then asks me for my Nedbank Acoount number which I do not have. I only have an MFC account. It has been going on now since I bought my car 11 months ago. It is very frustrating to get a statement from MFC.
