lack of concern

I signed up for a funeral policy in July 2014. After receiving my policy documents shoved under my door I realised my postal address was incorrect and requested this to be amended. And it was. Then I discovered I was being billed for TWO burial policies! My intermediary communicated this to Sanlam and to date they are still deducting payment for both policies. I have emailed Sanlam to sort this out, NO RESPONSE! I have called Sanlam , NO RESPONSE!!!! The call centre agent I spoke to on 28 April promised me feedback in 5 days, NOTHING ! I call back and the agent said she will escalate to management. AGAIN NO RESPONSE! I've been calling back every week and every week I get no positive feedback.Although you have THREE contact numbers AND. 2 email addresses I have heard nothing from them. My query is just ESCALATED! I've spent nearly R400 in phone calls(which I have record of my cell phone bill) and I wonder how long I must continue to pay for Sanlam's inability to pay attention to detail ?? I am requesting Sanlam to rectify this matter URGENTLY and that money wrongfully deducted, be refunded to me !
