Belling Format Oven 600XR?

I have a Belling Format 600XR and the glass on the hob got cracked. When I approached the local agent he said that the glass cannot be changed and we would need to but the whole hob which would not be worth it because you could buy the whole cooker instead.

However seraching on the web i did find the glass as a part no? what does this mean? Does it mean in fact the glass could be changed?
