Access to personal information, Unsolicited calls and Invasion of privacy by OLD MUTUAL

Is it a highly coincidental situation or internally coordinated and communicated amongst friends / colleagues that when you email customer service of Old Mutual to amend purely administrative policy information you then receive numerous time wasting unsolicited phone calls to my mobile from Old Mutual Sales staff. This annoying practice of Old Mutual must stop. Your sales people call and represent themselves as if I have requested a sales call. This occurred 3 times on the same day from 3 different so called professional OM Head Office sales staff. Ask your staff member Regis Chikadaya of OLD MUTUAL Cape Town HO, DFA? department to explain to your HR department how this practice works. The second caller was female and I asked her to "email her contact detail to me as I was busy". She failed to do this else I would have provided her detail as well.
