Waiting too long for response on savings account

I app**** for a nedbank save4me account for my minor son 6 days ago. I was told I would be contacted within 48 hours to complete the process. Following 6 days of no response, I have been to a branch and called the call centre but no one is able to assist me. The glen branch could not pick up any application and the call center can see an application but cannot tell me what's it's for or the progress of it. I would like to cancel the request because if there is this much confusion before even opening the account then I cannot risk my son's savings here.
