Fixed Multiple Deposits Account not allowing me to transfer to it.

I opened a fixed savings account which was a Multiple Deposits account and I used to do transfers on my own but now when I am trying to do it doesn't even appear and I called the the call centre to assist me and they referred me to branch and in branch they said they don't see any problem with the account yet I am struggling to do it on my app. Capitec please fix that for me!!!
