Investment Top Up

I currently have an investment with Sanlam which I wanted to top up, I called their contact centre and was taken through the documents which I needed to complete and process to follow. I did all that was required of me, sent back the alteration quote which I had completed and then was notified that the documents were sent to the relevant department (Nubamend) and they will be in touch. A month later I still haven't received any communication from them. Made a follow up and still nothing, I am sitting with money in my current account which I'd like to invest and Sanlam is not coming to the party. Bathong!!! Whilst I understand that this department is busy, but for me to wait a whole month without any form of communication??? For a whole month??? Guys come on now!!!
