Shares sold without the holders permission

Quilter Div. I have dealings with the call center and someone who said that they were a manager 4four calls and an email They sold my shares without my permission they say that they sent me a notification in the post this was never received so I was unaware of my shares being sold They said the default is if no reply is received they can sell the shares ( our postal service here in S Africa is almost nonexistent) The calls made to them and promises made to me have not been met and the escalation that the call center has said that they will do has not been met I under any circumstances as they are an investment to hand on to my family in the case of my beath one person said if I returned the money they would reinstate the shares I gave her my email address and she said she would email the account number to me this was over two weeks ago and I still do not have the email Management do not take calls in this organization the same as other corporate business When will they wake up to knowing that they have an obligation to us the customer call centers block all negative correspondence
