False Cover for 6 years

I have my portfolio with Old mutual since 2009, and since the passing on of my advisor I had no correspondence from Old Mutual. I decided to get a quotation from Liberty whereby I was advised that I am categorised as a regular smoker according to my portfolio with old mutual. Evidently I have been paying excess premiums as a smoker would normally pay more than a non smoker. I have not smoked a cigarette in my life and have been ********** for 6 years!
