Failure to activate policy

This is the third week I have made contact with Discovery Insure. I am an existing client with my and my husband's medical aid, life insurance, and vehicle insurance policies. I am now trying to activate my household insurance policy with Discovery. I spoke with two consultants initially (Dineo and Louise) and was provided with conflicting information as well as being required to resend documents, which I had already sent for this policy to be activated. I then escalated my query to the supervisor, Charissa last week, who assured me that she would assist as a matter of urgency and agreed that this poor service was unacceptable. I have sent her three emails since last week and still no response. I explained that the activation of this policy is paramount, but still no resolve with them. I am bitterly disappointed with the poor service I have received especially considering that I am a long standing client with multiple investments with Discovery. I would really appreciate resolve in this regard.
