Help!! Basically, i don't really know much about this biometric id??? Is it like a normal ID??? Do i need one or will i receive one???

I thought that i will get one after my biometric done in the post office and after my visa approved. And its been almost 4 weeks since my documents arrived and i havent received one. We've been trying to phone the number in the site to inquire, but it is always busy(answering machine). Atlast, last night i was able to get through to them, but the guy was so unhelpful(he pause alot in the middle of conversation). He asked my case ID number and said call tomorrow my computer hang up! I asked my husband to call back maybe they would entertain him. Unluckily, it's the same guy and even my husband find it difficult and frustrating to talk to him. My husband even tried to get his name, but he said we dont give names, not our policy! And said I dont need a biometric id.

We had a little bit argument with my husband because i believe i should receive a biometric id and my husband thinks i dont need one because my visa is approved already and he thinks its the one in my passport. (very funny situation...we just had a laugh after we are discussing about the man on the phone... )
