Bad Service

I have two savings policies with Old mutual which I wanted to cancel and had submitted all necessary documents on the 2nd May 2015. I was given a reference number for this submission which I have used a number of times when making enquries and no-one picks it up on the system. When I made this submission I was told that everything will be finalised within 7 - 10 days. It's now the 15.05.2015 still nothing and when I call the call centre today I am refered back to the branch at which I made the submission. I find it very appalling that a company the size of old mutual has such long lead times and when one lodges an enqury it takes more than a week to get a response.
