hold firm

I'm a little stuck... Click here to teach me more about this clue!

'refuse to budge' is the definition.
I can't tell whether this definition defines the answer.

'last company' is the wordplay.
'last' becomes 'hold' (I am not sure about this - if you are sure you should believe this answer much more).
'company' becomes 'firm' (I've seen this before).
'hold'+'firm'='HOLD FIRM'

'from' acts as a link.

Can you help me to learn more?
