After 3 months of debit orders I noticed that there were 2 debit orders debited from my bank account per month. I immediately tried contacting the advisor, who sold me the policy, on numerous occasions and left messages for him. Unfortunately due to the nature of my work at the time I wasn't at the means of going to a branch and sorting it out, after all Old Mutual initially came knocking at my door. I have tried calling the share call number but unfortunately many times the call is disconnected because of reception on my side. I have also gone onto the website where I am able to leave a contact number and a consultant will apparently call me back, well I'm still waiting. I then decided to let it be as it is an investment I the more you invest the better, so I thought.
