POLICY CANCELLATION PROBLEM

I've been your client since November, 2013. I decided to cancel my policy.I sent my 1st mail on 30/03/2015. No response.I sent my 2nd mail on 07/04/2015. No response. I only got the auto responses which serve as a proof that Clientele received my mails.The mails were sent to [Email Removed] as this mail address states on my Declaration and Auth Form from Clientele and I quote:Should you wish to lodge a complaint please contact the National Contact Center on Tel:*** or [Email Removed] My working hours are longer than Clientele's. I work on Saturdays. Written communication is also one of the ways to communicate. I checked this website and realized that many clients have problems with policy cancellation. I noticed that your Services Recovery Specialist V.Dlamini highlighted that policy administration queries should be sent to [Email Removed] So I sent my 3rd mail on 10/04/2015 at 6:37 a.m. No response. I need this matter to be attended immediately. Policy *** must be cancelled with effective date 30/03/ 2015. As per your \Policy T&Cs"I gave my 30 days' notice. NO MORE DEBIT ORDERS.The complaint could have been avoided if attended."""
