I submitted my application on the 20th of march and received notification that my withdrawal will be finalised within 15-17 working days. After 8 working days they requested my cancellation letter, banking details and banking details which I submitted with the application asking that acknowledge receipt of my documents. After 14 working days I called the call centre to confirm if they received my documentation and how long do I need to wait still just to get a response that I need to keep in mind I need to wait 15 - 17 working days and that my application has been send to SARS for a tax directive. So, I was fine with that just to get a SMS today, which is day 16, to say all documents have been received and my application has been send to SARS for a tax directive and need to wait for another 5 - 7 working days. I don’t know what is happening because my husband did the same application with Sanlam, and it literally took them 5 working days. Extremely poor service and a disappointed client
