Outsurance harassing their own clients

Have only been a client of Outsurancefor just over a year. Today was contacted by and agent with a "special offer" whereby by my premiums could be reduced or not paid for a couple of months if only I referred some family or friends to Outsurance, on which my reply was NO. Seeing as the agent on the phone seemingly does not understand what NO means I simply ended up canceling all my cover with them. I mean really , when you start badgering you OWN clients you should just give up. It is a pity I cannot delete all my information from their systems, but there is not a snow***** chance in hell I will do business with them ever again.
