Nedbanks Homeloans Dept is ***********

I sent a letter and all other required documents in march to replace my Nedbank life cover with a Old Mutual life cover. I phoned in a month later and it was not replaced. Last month, mid-month, I went to the Cresta branch again and they told me it wasn't replaced in earlier efforts and they will work on it. after a couple of days I called the contact centre and i was told it will be finalised in 72 hours. to my surprise I got my home loan statement beginning of this week and it has not changed still.
