Go into the shop, ask to speak to a manager, refuse to leave until a manager appears.

Explain to manager it is your legal right, if they say no or it's not, ask them to write that down, and sign it.

Failing that write to head office, send recorded delivery. Tell them you reserve the right to take legal action (you could do this through the small claims court online).

Legally speaking you could argue that Vodafone have failed to perform on the contract you have entered into, so there is no obligation on you to do so either. However, might not work and a high risk strategy.

I just got a lot of "I'm sorry sir but we are only allowed to ask you to send your handset in", my requests to speak to anyone senior were denied, then they hung up on me.

I was extremely polite throughout I might add- not so much as a hint of a raised voice, so hanging up on me (might have been a network issue- hah!) pissed me right off.

I'd dearly love to be rid of Vodafone- is there any way I could parlay this into dissolving the contract?

I'd happily buy my own handset and go to a pay monthly SIM.
