Policy detail change without holder consent

On 10 March 2015 just after 16:00 I phone Discovery insure for a quotation to add a vehicle to my policy.<br> We went through all the security questions, I supp**** all the vehicle information and the registered owner and most regular driver which is my wife.<br> Before the quotation was done our call was dropped. I did not get the name of the person helping me.<br> I phoned back and was answered by Zandile, after supplying my ID number he informed me that I am not authorized to add anything on the policy as my wife is the policy holder. He also informed me that if I want to change the policy holder we need to cancel the policy and start a new one.<br> My previous policy schedule that I have received on 7 August 2014 show that I am the policy holder and that this policy is in my name. I phoned again and was answered by Marie-Ann, I explained the situation to her and after a long discussion she forwarded the information to one of her managers. I asked that they give me feedback before 9:00 on 11 March 2015 as this is a serious matter to me, this did not happen.<br> How is it possible that they can change the policy holder on my policy without my consent?<br> How safe is my information with them?
