Virgin Media contract

A question about : Virgin Media contract

Moved house in February 2014 and haggled with VM for a better deal as I had them in my old house.Spoke to them and ended up with a really good package ( Ј33 a month for 12 Months on a 12 Month contract ) , as per email confirmation.Am just coming up to the end of my 12 Months special price/contract and wanted to contact them to see if they could keep the price nearer this figure than the price of Ј72 a month which my newly arrived bill is asking for.
Have got the email from them confirming it is a 12 Month contract but have also dug out the paperwork from when my services were fitted ( Feb. 2014) and it has 18 months as a contract.
My question is , should I contact them to try and negotiate a new contract stating my email confirming 12 Months or is it my fault for not checking the paperwork had stated 18 months ?

Thanks

Best answers:

• It's not a 12 or 18m contract, it's a 12 or 18m minimum term.
  I would go haggle based on the email stating 12m-what do you have to lose now that the price has reverted to the rack rate?
