Very poor customer service today through call centre

<p>I called today to get one of my nr soft-locked. I prefer fast efficient service... and was convinced to do Voice Password to avoid time wasting due to manual verification processes. So when I verified my profile with my voice, I came through to an agent who told me that he did not think that verification was enough and wanted to subject me to the whole verification process all over again... I then asked to speak to a manager to understand the purpose of Voice Verification... as it is pointless if the agent was going to do manual in any case. I must have experience asked to speak to a manager on 3 occasions... where the agent just refused and said goodbye to me and hanged the phone in my ear. Terrible terrible service.</p>
