Policy cancellation takes 3 weeks

On tuesday the 12/01/2016 I phoned Old Mutual regarding my policy cancellation and they requested me to send a letter which i did the same day, I got an automated email saying my request will be cancelled within 48 hours.I followed up on Monday the 18/01/2016 and still it wasn't cancelled and I was told it has been escalated. I then again followed up on 22/1/2016 I was told that they are going to escalate it, This is unprofessional and *********** of all the stuff at old mutual which brings a concern that they don't value their customers. I pledge with you fellow Old Mutual Customers or future customers not to do business with them, rather find another Insurance company that will put you first.
