Bad service

On the 04 March 2021 I made 2 applications to withdraw from my investment.I did the application on their whatsapp line and then I received reference numbers stating that I was gonna be contacted should there be more information required On the 11 March at about 12h00 I contacted customer care *** and I was able to be assisted 20min later. The lady then informed me that I included an incorrect policy no and whilst talking to her the line got cut off and she didn't bother calling back yet I verified all details. My main concern is the fact that I was sent a confirmation message that I was going to be contacted should there more info required and nobody bothered even when I got cut off they still didn't contact me yet they are called CUSTOMER CARE when there's no care being practiced.
