Still waiting respone

I called discovery insure, to notify them that i moved and bought a house and want to change adress , the call centre guy informed me that we need to go through the process of changing details on my portfolio, we went through the process when finished he informed me that he cannot do the change as a risk manager has to appeoved it due to the fact that the fence wall changed from a 6 foot brick wall to a 6 foot pre- cast wall and it will affect my premuims i informed him that i dont see the difference in premuim as the precast wall are more difficult to get over than a normal wall. I then said put me through to Risk manager so that we can sort it out after hanging on for about ten minutes i was informed that the risk managers are in meeting and will call me back within in 2 hours. 4 hours later and still no feedback from them and i called the complaints officer number on there website and just to get another voicemail at 14:30 in the afternoon that she is unavailable. So if i get hihack or get broken in i will not be covered .
