NO SERVICE NO CONTACT

For 5 months now I have attempted to get information with regard to my policy. Unsuccessfully. I have even "threatened" cancellation without response. Besides the many emails sent I have tried phoning customer care, complaints etc and even defaulted on a premium without response. Names and emails include service@oldmutual ( maybe I should try noservice@old mutual, Kanyisa Ncemane ( general manager customer solutions), Zaheer Gabru ( senior administrator) What am I expected to do - they do not deserve my 30 year old business I have given them! Would someone please respond!!! I even have a case reference number.
